Learn How to Perfectly Adjust Your Commercial Door Closer

Commercial door closer

Many business owners may not be aware that they can change the settings on their commercial door closers. These settings allow you to adjust the delay time before the door starts to close as well as the speed at which the door swings closed. You can also adjust the resistance of the door when pulling it open. 

Following a few simple tips can help you modify these features of any commercial door in your business.

Adjusting the Close Swing Speed

According to Accreditation Commission for Health Care (ACHC) regulations, every fire door in a healthcare facility must have an automated closing assembly. Since many other industries have also adopted this requirement, the majority of commercial and industrial doors come with these types of closing assemblies.

Each type of business will want to install a door that closes at a different rate of speed. Rather than manufacturing a unique door for each purpose, it makes more sense to equip the closing assembly with methods for adjusting the closing speed. This makes it easier to customize the door’s operation for the needs of your business.

You may not have noticed the features on the closer that allow you to adjust the close swing speed. Typically, there is a small screw labeled with an “S” to indicate that the screw controls the close swing speed. Depending on the type of screw the manufacturer installed, you can adjust the screw with a screwdriver, hex wrench, or box wrench. 

To speed up the door closure, turn the screw clockwise. You can slow the door by turning the screw counterclockwise. Make sure to use small adjustments and test them. Even a turn of a quarter of an inch can make significant changes to the close swing speed.

Changing the Latching Speed

If you have ever watched your commercial steel door close, you probably noticed that there’s a change in speed as the door closes to a gap of a few inches. 

This is a different closure speed that controls the force at which the door closes. If the door moves too slowly, it may not latch correctly when it touches the frame. This setting is the latching speed, and you can also adjust this feature.

As you look at the closer, try to find a screw labeled with an “L” to indicate the control of the latching speed. Similarly to adjusting the close swing speed on your commercial doors, turning this screw clockwise will increase the latching speed. 

Turning the screw counterclockwise will slow the latching speed. If your door slams shut too forcefully, you’ll want to decrease the latching speed.

Modifying the Back-Check

As IFSEC Global explains, the automatic closing of commercial and industrial doors is an important safety feature. During a fire, closing doors as individuals flee to safety will help slow the spread of smoke and fire. 

However, people may be too panicked to remember to close the door behind them. An automatic door closer addresses this issue by ensuring the doors will close on their own.

This feature either uses a spring or a hydraulic mechanism to control the closing of the door. Either type of door can be difficult to open if the pressure is set too high. 

To change the pressure involved in opening a commercial door, you will need to adjust the back-check. Look for a screw labeled with a “B” and turn it clockwise or counterclockwise to modify the strength needed to pull the door open.

Setting the Delayed Action

Another feature of commercial and industrial doors is the delay action, controlled by a screw labeled with a “D.” This is the time a door will remain open before it starts to close. Turning the screw clockwise will decrease the delay time, while turning it counterclockwise will increase the delay time. 

You may need to adjust this setting if you need a door to close as quickly as possible. You’ll want to increase the delay time if packages are usually carried through the doorway. Again, change this setting in small increments to ensure you can get the exact delay time you want.
