Performance and Durability – A door closer is a mechanical device that closes a door, in general after someone opens it, or after it was automatically opened. Choosing a door closer can involve the consideration of a variety of criteria. Door Closers are available in a variety of architectural finishes, door closers can be surface-mounted or concealed. Door Closers often feature dampers that offer control over the closing force and speed.
There are four styles of interior door-closer:
- Concealed in frame
- Concealed in floor
- Concealed in door
Door closer adjustment requires knowledge and an ability to climb up and down a ladder several times. Most of the adjustments are implemented by opening and closing hydraulic valves. When it comes to turning the screws that operate these valves, a little goes a long way. A turn of five degrees can significantly increase or decrease closing speed.
