You probably don’t think about it when you walk through the door, but commercial door closers are an essential piece of door hardware in any commercial building. They are so important in fact, there are building codes and regulations specifying their use. Door closers must meet fire code and be ADA compliant.
Commercial door closers are not like the single-cylinder piston on your screen door at home. There are four different settings on a commercial closer that determine:
- Sweep Speed (speed that the door closes up until latching)
- Latch Speed (force used to close the door to latching)
- Spring Tension (how hard it is to push the door open)
- Back Check (resistance to protect wall when door is fully open)
A commercial door should close within 5 to 7 seconds. If door closer adjustments are not correct, it can cause damage to the latch, hinge – or someone walking through the door! A Goffstown Lock and Key, we find it surprising how many times a customer will call thinking their door is broken, when all it needs is an adjustment to the door closer.
It is possible that a door closer fails because it is not the right piece of equipment for the application. There are models that range from light duty to heavy-duty, depending on the use cycle of the door. At Goffstown Lock, we will properly size and install the best quality commercial grade door closer for your commercial building – so you don’t have to call us back to fix something else!
