Overhead Door Closers: Functions and Adjustment Options

Overhead door closers are an essential part of a building’s security system. They are used to ensure that the doors of a building remain closed and secure. A door closer is a mechanical device attached to the top of the door. 

Its purpose is to control the speed at which the door closes after it has been opened. Door closers are designed to close the door at a specific speed rate and keep the door securely shut when it is not in use.

What Are Its Working Principles and Functions?

The working principle of an overhead door closer is relatively simple. When the door is opened, the closer is activated and exerts a downward force on the door. This force is called the “closing force.” As the door is opened, the closer will begin to move downward, applying pressure to the door until it is fully closed. Once the door is shut, the closer will remain in the same position, ready to close the door again when it is opened.

The function of a door closer is to provide security for a building. Controlling the speed at which the door closes ensures that it cannot be forced open or remain ajar. This helps to protect the building from unwanted visitors and potential intruders. 

What are Its Adjustment Options?

The overhead door closer is an essential piece of hardware for front doors. It helps keep the doors closed, secure and properly positioned. In addition to providing security and convenience, the door closer can also provide additional features and functions that can help improve the doors’ overall performance. 

We will discuss the adjustment options and special functions of the overhead door closer for doors below:

1. Spring Tension

This can be adjusted to either increase or decrease the force needed to open and close the door. If the spring tension is too low, the door may be too easy to open, while if it is too high, the door may be too difficult to open. Adjusting the spring tension can help ensure that the door functions properly and remains secure.

2. Latch Speed

This can be adjusted to determine how quickly the door will latch when it is closed. A slower latch speed is often desirable for safety reasons, as it allows more time for the door to close completely before it locks. On the other hand, a faster latch speed allows for quicker closing of the door.

3. Delayed Closing Feature

In addition to these adjustment options, the door closer also has several special functions. One of these is the delayed closing feature. This allows the door to remain open long before it automatically closes. This can be useful in preventing drafts in the house or allowing more time for people to enter or exit the house before the door closes.

4. Emergency Release Feature

Another special function of the door closer is the emergency release feature. This allows the door to be opened from the inside without using a key or other unlocking device. This is especially useful in emergencies, such as when the house is on fire, or someone needs to escape the house quickly.


Overhead door closers are an important part of many front doors. They provide convenience and safety by allowing the door to close automatically after a user opens it. Door closers are usually mounted on the top of the door and work by using a spring, hydraulic, or pneumatic system to generate the force necessary to close the door. Door closers are a great addition to any door, as they provide convenience, safety, and are easy to install and adjust.
