Doors that close effortlessly, with a slight movement of the hand, give solidity to the car and provide additional comfort for the driver and passengers. Smooth closing is provided by special mechanisms - closers. These devices can be standardly installed by manufacturers in premium cars. However, owners of less expensive vehicles can install universal-type door closers on their own.
What is a door closer in a car
The door closer of the car provides reliable closing of the vehicle. Thanks to the installation of the mechanism, the owner will not have to re-open and close the doors when they do not fit snugly against the body. If the force applied by the person was not enough to close the door, the device will complete the process on its own. For example, small children do not always cope with the heavy and bulky doors of SUVs. In this case, the closer mechanism will help them.
Universal closer for cars from Slamstop.
Also, the car closer will provide soft, smooth and silent closing. The driver will no longer have to ask passengers to quietly slam the door. If the mechanism is installed in the tailgate, then only a slight pressure on the door is required to close it. Then the device will complete the task on its own.
Benefits of using the design
It becomes clear that installing a door closer in a car has many advantages, which include:
- dense adjoining of doors to a car body without application of efforts;
- extending the life of door mechanisms;
- increased comfort;
- better heat and noise insulation;
- protection against dust and moisture.
The advantages include the compact dimensions of the device: the installation of the door closer will not be noticeable in the cabin.
What cars are equipped with closers
Despite the convenience of the system, door closers are not installed on all cars. Most often, the mechanism is used in premium cars from manufacturers such as Mercedes, Audi, BMW and other major brands.
If the car does not have a regular closer, the car owner can install it himself. In this case, you should purchase a universal mechanism suitable for any model of vehicle.
Principle of operation
The door closer is activated at the moment when the door is closed on the first latch of the car lock. To determine whether the car is closed or not, the door position sensor allows. If there is a gap between the door and the body, the electric sensor will work, after which the closer, using a special cable, will pull the door until it is completely closed.
If there are problems in the operation of the door closing mechanism, the reliable operation of the closers cannot be fully ensured.
Device and types of car door closers
The mechanism that ensures tight closure consists of several main elements:
- a sensor that determines the position of the door;
- electric drive, providing attraction of the door;
- a control unit that receives a signal from a sensor and sends a command to the electric drive.
On modern cars, you can find two main types of door closing mechanisms.
- Electric is the most common option. It, in turn, can be based on the base:
- worm gear, which is installed on SUVs and crossovers instead of regular gas stops;
- clamping mechanism (much more common).
- Hydraulic mechanism, which includes an autonomous hydraulic system with a pump, electronic pressure control and a complex actuator. This device has a high cost, so it is installed only on expensive sports cars.
Closers can also be classified into:
- universal;
- created for the car model (installed regularly at the factory).
Universal devices can be installed on any vehicle, regardless of its make and model.
What is a pinless door closer
A pinless closer can also be installed on almost every car. To mount the mechanism, you do not need to cut additional holes in the doors: it is installed in a standard lock. In this case, the mechanical part of the lock is replaced by a device with an electric drive. Then the 12 volt power supply is connected. If the installation is done correctly, the pinless door closer will provide the owner with smooth closing of the doors.
The pinless door closer is installed in the standard hole of the lock. A door closer for cars is a convenient device that is installed as standard on premium segment cars. If the car does not belong to this class, the car owner can always install a universal closer on his own, which will also monitor the smooth and tight closing of the doors.
An open door is the cause of drafts and heat loss in the room, so it is extremely important to take care of its timely closing. If you can put a simple spring on a swinging canvas, then this option is not suitable for coupe-type structures. The way out of the situation can be a closer for a sliding door, which will ensure smooth closing of the sash and allow you to maintain a comfortable microclimate of the interior space.
How a sliding door closer works
Closers for compartment doors are mechanical devices that prevent a sharp collision of door leaves. Structurally, the product is a metal case, which houses the damper, lever and piston system. On its outer surface there is a special adapter that has an auxiliary effect on the operation of the closer.
When the sash is closed, the adapter presses on the lever, which causes the damper to actuate. As a result, the door slows down, and when the damper reaches its end position, the leaf stops completely. The damping of the sliding door closer contributes to the repayment of the applied force, so the leaf closes without a characteristic knock and force impact.
Installation of a sliding door closer can be carried out with an argument both in one direction and in both directions. As a rule, devices are designed for door structures weighing 60–100 kg, made of laminated panels, PVC, veneer, glass, aluminum profiles, solid wood. Most often they are mounted in rooms with high traffic, where the constant opening and closing of the leaf leads to a rapid loss of performance of the entire door system.
Types of closers
The range of closers for compartment doors is not as wide as for conventional swing systems, but it is quite enough to choose exactly the option that suits best. Devices differ in the installation method, mechanism design, location on the door, as well as in design, color and price category.
According to the installation method
Depending on the installation method, there are two types of sliding door closers:
- Overhead - mounted on the outer surface of the door leaf, while most of their components are open to access.
- Built-in - installed in the door profile, door frame or in the floor. In most cases, such products require the creation of a cutout in the structure using a cutter, where the body with the mechanism is inserted.
By location
Different types of closers for compartment doors can be located in different places of the door system. Based on where the products are mounted, they are divided into two categories:
- Upper - for placement at the top of the door structure.
- Lower - mounted at the bottom of the door.
According to the principle of work
The functioning of all devices is based on a spring structure, however, the principle of their operation may vary slightly depending on the structural features of the mechanism. In this regard, the following sliding door closers are distinguished:
- On a standard sliding rod - the lever moves simultaneously with the sash along a special groove.
- "Knee" - the lever has a folding structure and consists of two axes that bend like a knee when the sash turns.
- On the cam - the design has a cam, which, when rotated, exerts pressure on the spring.
- Toothed - products are equipped with a rack and pinion mechanism acting on a spring.
Consumers are offered a wide range of additional devices that allow for the full operation and smooth running of the sliding door. In particular, the catalog of the TBM-Market online store presents high-quality universal rollers with a closer, designed to move the web in two directions.
Benefits of using closers
The benefits of installing a sliding door closer are undeniable. The device contributes to the soft silent operation of the blade and provides many advantages in use:
- Protects the door from shock when closing. Strong pops often lead to mechanical damage to the canvas and disrupt the comfort of living. If you put such a device, then you don’t have to worry that due to the high application of force, the door will prematurely fail or interfere with the peace of neighbors and households.
- Ensures the safety of the door leaf during operation. If the mechanism is correctly adjusted, the door closes softly and smoothly, so that no one pinches their fingers or clothes.
- Reduces heat loss in the room. The automatic closing of the sash helps to retain heat in the cold season and prevents the penetration of drafts. In the process of operation, closers for compartment doors tightly press the door leaves to the frame, providing good sealing of the room.
- Allows you to adjust the speed of the movement of the sash. Many models have auxiliary functions such as adjustable speed and selective closing force, which allows you to adjust their operation depending on the season. In particular, in winter they will close faster, minimizing potential heat loss.
Criterias of choice
When planning the purchase of a sliding door closer, it is advisable to pay attention to its technical characteristics, which can be found in the attached instructions. Products with incorrectly selected parameters can lead to premature wear of door fittings and significantly reduce the functionality of the leaf, therefore, when choosing a device, it is recommended to consider the following criteria:
- The type of traction mechanism installed in the body - as mentioned above, modern manufacturers introduce closers with several types of mechanisms to the market, which largely determines the place of their installation. In particular, devices with standard traction are mounted directly on the canvas, and devices called "knee" are mounted on the door frame.
- Door dimensions - the wider and more massive the door leaf, the more powerful the door closer should be chosen for compartment doors.
- Temperature conditions - many products function smoothly in the range of -40 ... + 70 ° C, but some models lose their technical properties at low temperatures. For this reason, when buying a mechanism for unheated premises, it is necessary to take into account the conditions of its operation.
- Installation method - for glass doors it is advisable to buy devices with a floor mounting method, for all others, both floor and top are suitable.
- Design - To ensure that sliding door closers fit perfectly into the overall interior design, it is best to give preference to kits that match the color palette of the door structure.
- Maintainability - in case of failure of the structure, it should be easily replaced with a new one. In the catalog of the company "TBM-Market" you can find universal sets of rollers with a closer, suitable for all types of compartments. Our qualified staff will help with the purchase and arrange its delivery in Moscow and the region.
Door closer installation
The usual waybill is easier to install, while the hidden one requires professional skills, dexterity and special tools. In general, for the installation of any product, it is necessary to prepare a tape measure, level, drill and screwdriver. Before proceeding with the installation, you should mark the holes for the fasteners, which are determined from the lower height of the doorway. Further installation involves the following steps:
- In the marked places, holes are drilled with a drill (if a hidden door closer is installed, then cuts are made under the body).
- Before installing the door closer for compartment doors, pull its carriage (bring it to the erected state).
- Using a screwdriver, screw the body of the product to the end of the canvas.
- Similarly, a hook is attached to the upper guide.
- Perform device adjustments. There are two screws on the body that are responsible for the speed and force of closing the sash. They are carefully rotated until the required operating parameters of the door are reached.
If the mechanism is installed correctly, the sliding door closer will last a long time and reliably protect the premises from drafts and extraneous noise. Its use will ensure smooth closing of the canvas and will make the operation of the compartment more comfortable and easier.
Types and principle of operation of devices: top closer
No one likes a slamming door, but it should close tightly to avoid heat escaping from the room. For the noiselessness of the process, a door closer is installed.
Such designs replace the installation of door springs, which, when closing the structure, create a lot of noise. The types of devices, their features and installation methods will be prompted by the article.
Automatic element: device, characteristics and principle of operation
The main working element of any closer is a high-strength spring that enters the cylinder. When the doors are opened, it accumulates energy by contracting, and when released, it returns the product to its initial closed state.
For smooth closing of the opening, the design has an oil shock absorber. The built-in valve system facilitates the flow of oil when opening from one chamber to another, and when closing back.
With their help, the speed of movement of the oil, and hence the closing, is regulated. The necessary smoothness of the process is given by the viscosity of the shock-absorbing liquid, this contributes to the silent closing of the door.
The design may have one or more shock absorbers, which does not change the essence of the device. The working spring in different products is driven by its own mechanism, which determines the type of door closer.
Depending on the device, several tasks can be performed during installation:
- Adjust the closing speed in two ranges - with acceleration when slamming.
- Protect the canvas from hitting the barrier.
- Fix the structure after its opening.
Device types
Types of closers are classified by location, which can be:
- Upper. Installed at the top of the canvas. Drive type:
- crank, the design uses a spiral spring and a hydraulic piston, which are located in separate compartments. These are fairly simple devices that do not have the ability to control the movement of the door, or other changes. In demand for heavy products;
- jagged. This is the most common design, consisting of a toothed gear meshed with a piston and moving it along the axis when the door is torn off. When it is opened, the closer lever moves in an arc. The part of the lever screwed to the body of the device is located perpendicular to the toothed gear, the axis of which moves vertically through the closer. The teeth of the gear mesh with the teeth of the piston. Moving along the axis, the gear moves the piston in a horizontal position, clamping the spring. In the same way, energy is stored. Closing relaxes the spring, which pushes back on the piston. Rotating, the gear pushes the structure to move with the lever, closing it;
- with sliding bar. This is not the most successful design option, in which there is no shoulder for transmitting a large force, which leads to not very reliable operation of the mechanism;
- cam shaft. The cam, which looks like a symmetrical or asymmetrical heart, also serves as an axis. When opened, the element evenly compresses the spring with a piston. When closing, the spring is released, the opening piston moves in the opposite direction, returning the cam to its original position, the door is slowed down by the brake element.
- Floor closer. Located on the floor. This type of installation must be taken into account during the construction phase. In this case, the weight of the door is held by the lower axis, which moves towards the other axis of rotation.
The design is used for products weighing up to 300 kilograms.
- Ramny. This design is built into the frame or, and its principle of operation is the same as that of the floor ones. In this case, the mass of the door is carried by a support that is built into the floor. Rotation is transmitted to the canvas from the axis of the closer through a lever built into the top. When opening with a lever, the heart-shaped axis rotates. Depending on the direction when opening, it begins to put pressure on one of the rollers, which compresses two springs. When closing, the whole process goes in the opposite direction.
By design, products are divided into:
- Linear. In such an element there is no knee or part for customizing the product.
- knee. The design has a “knee” that bulges out when moving the canvas. These are the most reliable and simple devices among lever mechanisms. There are two mounting methods:
- the body of the leading mechanism is mounted on the canvas, and the lever device is installed on the box;
- a reverse mounting option is also possible.
Classification of mechanisms
To get acquainted with what Russian-made closers exist, you need to study GOST 5091-78. The main criteria are technical characteristics, or the efforts applied by a person when closing the structure.
According to GOST 5091-78, all door closers are divided into 7 classes:
- EN1. Used for sashes with a width of 750 millimeters and a weight of up to 20 kg.
- EN2. The ideal device for canvases 850 millimeters wide and weighing up to 40 kg.
- EN3. Devices for leaf widths of 950 millimeters, weighing up to 60 kg.
- EN4. Designed for canvases, the width of which is 1.1 meters, weighing up to 80 kg.
- EN5. Are established on shutters 1,25 meters wide, weighing up to 100 kg.
- EN6. Devices of this class are designed for doors with a width of 1.4 meters, weighing up to 120 kg.
- EN7. Such mechanisms are ideal for canvases 1.6 meters wide and weighing up to 160 kg.
According to GOST 5091-78, the force that must be applied when closing is indicated, measured in Nm (Newtonometers). The Door Closer company, in its certificate for manufactured products, indicates the force in Nm. At the same time, models of mechanisms can be of the same class, and adjustable, with the ability to adjust the application of efforts when opening.
In addition, GOST 5091-78 gives recommendations on closers for their operation, taking into account the temperature range. This is due to the fact that the oil used to lubricate the structure changes its viscosity under the influence of temperature. For outdoor use, it is recommended to install frost-resistant devices, using low-temperature oil, and special seals, which is contained in the product certificate.
GOST 5091-78 indicates another feature that should be taken into account when choosing a door closer - the transmission of torque.
Device selection
Tip: Before choosing a closer, you should get acquainted with the standards that determine the efforts developed by him when using them. They comply with European standards.
The greater power of the door closer corresponds to its higher class.
For example:
- The product of the highest class is selected for.
- The low-class door closer is installed on a lightweight product.
- Designs of 3-5 classes are used for simple entrance doors installed in interior spaces.
When choosing a door closer, parameters are taken into account, external factors are taken into account, for example:
- When operating the front door, which is often exposed to lateral wind loads, the canvas should be equipped with high-class products, which will increase the life of the door closer.
Tip: If two different classes of products can be used in terms of size and weight of the product, preference should be given to high-level elements, which will provide a greater margin of safety, and hence longer operation of the device.
- It is not necessary to consider only power when choosing a product. This does not always indicate a large installation load. If such a closer is installed on a PVC door, an additional load will be created on the hinges, due to which they will quickly wear out.
- The plastic door with powerful elements is difficult to open, this will create additional discomfort when using.
- When choosing a closer, its frost resistance should be taken into account. There are models that operate at extreme temperatures ranging from (-45°C) to (+ 70°C).
- Attention is drawn to the speed of movement of the door system. For example, for fire protection structures, devices must have a high closing speed, and when used in a house, a slow one is preferred, especially when the elderly and children live. In public places, it is better to install devices with an opening braking function, which will prevent the sash from hitting the wall.
To familiarize the buyer with the additional features of the product, a certificate for the door closer is offered. Its presence is a guarantee that the purchased product is of high quality.
Tip: When choosing a device, you should ask about the certificate. This will give greater confidence that the selected device will work properly for many years.
Overview of popular models
Below is an overview of door closers of the most famous foreign manufacturers that produce high quality products:
- Dorma. This is the mechanism of a German company, the peculiarity of which is the presence of a sliding rod. This design allows you to hide the knee of the traction mechanism, and not spoil the appearance of the door.

- Sliding door closers. Such devices are often used in public places: shops, hospitals, offices. The advantages and disadvantages of the device of such structures are given in the table:
| Advantages | Flaws |
|
The main disadvantage of using such models is the presence of protruding spring-loaded pins, which are easy to catch and break the device. To prevent this, it is necessary to place the product at the highest possible points, but this may reduce the strength of the structure. |
Mounting the mechanism
When purchasing a product that will be installed on the door with your own hands, you must keep in mind that the kit should include:
- Closer.
- Lever pull.
- Hardware for fasteners.
- Scheme or drawings of a closer for mounting the structure.
Fittings can be installed on the input block: on the box and on the canvas, which depends on the purpose of the structure.
Installation happens:
- Internal, as in the photo. This is the most common way to install structures for external doors, while the product is attached to the opening.
- outdoor.
The life-size installation diagram included in the kit allows you to install the accessory with high quality and avoid errors in the process.
For this:
- The installation diagram is glued to the door with adhesive tape.
- Further actions are performed according to the instructions offered by the instruction:
- Markup is being done.
- Holes are drilled.
- The body is attached.
- The linkage is mounted.
These are two halves connected by a thread.
- The lever is adjustable in length, which determines the opening angle of the door, approximately 90°.
- With the correct installation of all structural elements, the device will work efficiently, without failures.
In more detail, the installation of closers shows the video in this article.
Closer setting
Correct adjustment of the installed elements can be performed if you deal with the screws that are part of the structure.
Many models have special screws located on the decorative cover of their case. On some, the screws are located on the front side of the case and are marked with numbers 1 and 2. Screw 1 regulates the change in the opening angle of the door, it can reach 180 °. Screw 2 changes the closing speed of the sash.
When adjusting the closer:
- The opening angle of the door leaf varies from 90° to 180°.
- Closing acceleration is corrected by adjusting screw 2.
- The door opens to the working angle and is released.
- By turning the screw 2, the smooth running of the door leaf is adjusted to the last 15° in order to guarantee its reliable closing.
- You don't have to put a lot of effort into making adjustments.
- After 1/4 turn of the screw, the doors will close slowly.
The closer can be used for a long time if the adjustment is done regularly. It must be borne in mind that forcibly holding the door for ventilation and propping it up with various objects can lead to an increase in the load on the glands and the closer piston.
This will cause the oil to be squeezed out of the housing and the closer to fail. Only a specialist will help answer the question of how to fill the door closer correctly. Each design has its own characteristics.
Closer Care
To maximize the life of the door closer, you need to maintain the serviceability of this mechanism, regularly check the condition of its main parts:
- To avoid problems with the appearance of corrosion, regular processing of metal fragments and lubrication of them for smooth running should be carried out.
- It is necessary to periodically adjust the settings in accordance with the parameters of the door.
- Nothing should be placed under an open door.
- You can not pull the door "toward yourself" to speed up this process.
- It is contraindicated to "help" the door close by holding it.
Whether it will be a built-in door closer or any other type of it, with proper installation and operation, such a device will allow you to control the process of opening and closing the structure. This will prevent glass from breaking, and sometimes the walls in the house falling out when metal doors are installed.
Convenient thing - closer
Closers are installed on those doors that are often used, in other words, they open more often. They can be placed as on the front door to an apartment, to a house, they are used for metal doors, for example, to an entrance, in various institutions. In hospitals closers installed on glass doors. They are used for fire safety purposes in the doors of "skyscrapers", so that in case of fire they can be tightly closed and the smoke does not "leak" into other rooms.
Mechanism from A to Z
Recently, the technology and design of door closers has improved markedly. This fact made it possible to achieve low prices for devices, which in turn made door closers very popular. One of the most sought-after companies, which is guided by the principle "price equals quality" in the manufacture of door closers, is Apecs. Devices of this brand can be bought for a variety of doors: from glass to metal.
The first, most primitive closer that everyone has encountered is the simplest spring. While it is capable of closing doors on its own, it has a colossal disadvantage. The spring cannot close the door smoothly, it has no adjustments, so it constantly pops. This leads to the fact that the doors are very worn out. They have to be changed more often.
Today, modern hydraulic door closer technology is able to close the door smoothly and silently. Although the principle of their work is not very complicated. The effort that a person makes when he opens the door compresses the spring, which is located in the metal case of the closer. This spring, when unclenched, closes the door itself. The force that is transmitted through the gear mechanism to the bar contributes to smoothness.
It is the smoothness and softness of closing that is one of the main advantages door closer. In addition, it allows you to adjust the closing speed. Smoothness and noiselessness are ensured by the unique device of the door closer. It is equipped with a hydraulic special mechanism. Inside the body of the device is a working cylinder, which is filled with either oil or a water-glycol solution. In turn, a piston moves inside this cylinder, which pushes the liquid through a pair of channels, the liquid flows from compartment to compartment, which is a damper and contributes to the smooth operation of the door closer.
Also, the door closer device involves adjusting the closing speed. This is possible due to the cross-section of the bypass channels and with the help of control valves (usually the screws for adjustment are brought to the body of the door closer). This design of the device is simple and technologically advanced, which, with the mass production of door closers, allows you to get a high-quality, durable, inexpensive product.
Which conductor to choose?
To choose exactly what you need to know, not only the device of the door closer, but also the parameters of the door itself. Its weight, width, air resistance when closing and opening the door, as well as the wind load on it. With an increase in the mass of the door, its inertia increases, this affects the speed of closing the door. Therefore, at a large wide door, the closer must be more powerful.
With the development of technology, human life has become much easier. With such a simple device as a door closer, you will forget about the need to double-check if the doors are closed. Today, devices are produced in several forms and are represented by goods from different manufacturers, differ in belonging to different price categories. We will figure out how to mount the door closer and adjust the door closer, how long this process will take and how difficult it is.
The main types of mechanisms and their internal structure
To choose a closer option for a door, you first need to understand the types of mechanisms and their intended purpose. The choice should be based on the parameters of the door, namely? width and weight of the structure. In addition, consider the temperature regime of the room where the installation and operation of the element is planned.
The main options for auto-closers include:
A feature of the street closer for the door is that it is equipped with a special mechanism lubricated with a liquid that increases resistance to high temperatures. That is, if you install such a closer designed for interior doors or used in installation on entrance doors from the inside, from the outside, then its operation will deteriorate significantly, and its service life will decrease.
The principle of operation of the door closer
This device is similar in its work to the spring mechanism, which was previously installed on gates and doors. The disadvantage of such a device was far from smooth closing, and sometimes pops of the closing structure. As soon as modern automated systems appeared that ensure the smooth running of the door, the problem with the formation of noise was solved by itself.
The main working part of the closer is a spring and an oil shock absorber, which is responsible for a smooth ride. The oily liquid circulating inside special valves flows from one chamber to another.
Features of mechanisms
Among the distinguishing characteristics of closers are:
- Oil circulation occurs through a hydraulic system, adjustable valves.
- Smoothness and noiselessness at opening/closing of a door is provided thanks to a viscous consistence of oil.
- Depending on the type of device, the strength and speed of the mechanism may vary.
It is easy to adjust the parameters of the closer with the help of special adjusting screws. The tighter they are clamped, the slower the fluid flows inside the cylinder. Having carefully read the principle of operation of the mechanism, it becomes clear that it is not so difficult to remove and adjust the door closer.
How to mount and configure the door closer yourself
The main purpose of closers is to smoothly close the front door. When installing, make sure that the body of the product is on the inside of the room, which makes it impossible to dismantle the product from the outside. This contributes to additional protection of the mechanism from the penetration of moisture, dust, dirt.
Mounting tools
During the installation you will need:
- Drill.
- Ruler.
- A simple pencil with a soft lead.
- Screwdriver.
There is no need to buy fasteners separately, they are included in the delivery of the door closer.
What does the installation process look like?
Some of the manufacturers add installation templates to the product kit with life-size images of all parts of the mechanism and the intended locations of holes and fasteners.
Having studied the template and the details of the installation of the mechanism, they proceed directly to the process of installing the device. First, the body is fixed, which, at the second stage, is connected to the traction lever of the structure. Following the instructions, you will see that the installation technology is not difficult and takes very little time.
Please note that the closers are structurally different, the location of the adjusting screws also varies.
Features of adjusting the door closer
The adjustment is carried out according to the same scheme, regardless of the design of the closer. By turning the screws clockwise, the speed of the mechanism and its strength is increased or, by turning the screw in the opposite direction, the door closes more slowly.
When working with this design, try to turn the screws slowly and carefully - this is one of the recommendations of experts.
To tighten the screw, it is enough to make a quarter turn. By knocking off the balance and strongly tightening or unscrewing the screw, you run the risk of completely upsetting the operation of the mechanism, which as a result will be problematic to restore.
Incorrect adjustment of the door closer leads to its breakdown. This is worth paying attention to.
How to properly adjust the door closer after installation
This procedure is carried out in order to obtain the optimal rate of closing the front or street door. Adjusting the opening speed, as mentioned above, is carried out using screws located on the front side of the case and hidden under a special protective cover, which is especially good when installing the mechanism on an interior door. So the design looks more aesthetically pleasing.
By setting the system for slow closing, the owner will be able to avoid damaging the walls, and the presence of additional functions for adjusting the door closer of the plastic opening door will allow you to configure the optimal mode of operation of the device.
Features of self-closing devices
Where to install this kind of clamps:
- on the entrance door;
- where the intercom is located;
- on structures that restrict the access of outsiders to the entrance;
- on other door structures of the entrance and interior type, if necessary.
Thanks to this mechanism, the door closes completely, and opens only when using a special key. A closer with a delay function is an indispensable device for door structures in public places, which facilitates access to the interior of the room for people with disabilities. This feature allows you to set a delay of 30-40 seconds.
