Commercial door closers

Believe it or not, there’s an art form to crafting the perfect tension in a commercial door closer. A properly functioning door closer is a mechanical device that will slowly close and latch the door. Sometimes the door closer needs adjustments and repairs when the spring tensions or the hydraulic fluid cause problems.

Symptoms of needing adjustments made on the commercial door closer:

  • you notice parts coming apart
  • there’s a spot of oil on the ground at the threshold of the door
  • the door swing speed is too fast or too slow
  • the door is hard to lock.

Depending on the type of closer, there are different adjustments that can be made to fix your problem. Some closers feature back check adjustment controls, latching speed controls, and delay action controls.

Whether your commercial door is glass, fiberglass, wood, aluminum, or steel, door closers are specific to each type. Most of all, the size, weight, and type of door will determine what type of door closer you need and where it needs to placed. In order for your commercial door to work properly, the door closer must be in good working condition and the right one for the job of operation.


Diagnose the problem of your commercial door closer:

  • Does the door easily fling wide open? Prevent this by fixing the back check adjustment controls.
  • Is the door not latching securely? The latching speed controls feature fully shuts the door for you.
  • Need to allow more time to walk through the door? The delay action feature allows the door to close steadily to allow time to enter and eliminates the need to pull the door shut after closing.

You should have a professional adjust your door closer to allow the perfect door opening and closings.

Panic bars are installed on commercial door hardware. It’s a spring-loaded metal bar that unlatches a door when pushed from the inside leading to the outside. They can be locked so that people can exit freely and locks behind them


Having properly working panic bars provides vital safety of everyone who’s within the building. There are actually laws in place to ensure people can safely and immediately leave your establishment in the event of an emergency.
