Check for a hold-open arm
Some closer arms have a hold-open setting, often a small nut or lever on the arm. When it's engaged, the door stays open past a certain angle. Loosening or switching it off lets the closer pull the door shut again. Fire-rated doors generally aren't allowed to be held open this way unless they use an approved release device.
If it won't close all the way
- The latch speed is set too slow, so the door can't push past the latch
- The door rubs the frame because hinges or pivots are worn
- Air pressure from the building's ventilation holds the door back
- The closer is too weak for the door's size or weight
- The closer is leaking and has lost its fluid
Adjusting the closer
Most closers have separate valves for sweep speed, latch speed and backcheck. Small turns make a big difference, and screwing a valve out too far can let fluid escape, so adjust a quarter turn at a time.
When to call us
Call if adjustments don't help, the closer leaks, or the door drags on its frame. We fix the cause, whether that's the closer, the hinges or the door alignment.
Questions
Is it okay to prop a door open with a wedge?
Not on a fire door, and not for long on any door, since forcing a closer open wears it out. Ask about a proper hold-open arm or magnetic release instead.
