About this door closer
A door closer controls how a door closes and latches, so it shuts fully and safely after each use. Commercial closers have separate adjustments for closing speed, latching speed and backcheck, which slows the door if it is thrown open. The arm and mounting (regular, parallel or top jamb) depend on which side of the door the closer goes and whether you need hold open.

Questions and answers
How do I pick the arm and mounting?
Regular arm mounts on the pull side; parallel arm mounts on the push side and is common on exterior and high-traffic doors; top jamb mounts on the frame stop. Hold open and cush arms add a hold-open or a stop.
What size closer do I need?
Size depends on door width, weight and location. Many closers are adjustable across sizes; check the specifications or ask us.
