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.
Features
- Closers for interior and exterior doors shall be full rack-and-pinion type with cast aluminum alloy shell.
- Closers shall be surface mounted and shall project no more than 2-1/8" from the surface of the door with standard cover.
- Closers shall be non-handed to permit installation on doors of either hand.
- Closer fluid shall contain lubricity and anti-oxidation agents.
- Closer fluid shall maintain stable viscosity to allow door closer to perform in temperatures ranging from extremely high to as low as -40°F.
- Closers shall have multi-size spring power adjustment to permit setting of spring from size 1 through size 6.
- Closers shall have two non-critical valves, hex key adjusted, to independently regulate sweep speed and latch speed.
- Closers shall have adjustable backcheck intensity controlled by a hex key adjusted valve.
