[edit] Closer
Manual door closer.See main article: Door closer
A door closer is a mechanical device that closes an door that is open.
[edit] Hinges
A typical peephole in a door, allowing the person to see who is outside the door without opening it.See main article: Hinge
A hinge is a component that attaches one edge of a door to the frame, while allowing the other edge to swing from it. It usually consists of a pair of plates, each with a set of open cylindrical rings (the knuckles) attached to them. The knuckles of the two plates are offset from each other and mesh together. A hinge pin is then placed through the two sets of knuckles and usually fixed, to combine the plates and make the hinge a single unit. One door usually has about three hinges, but it can vary.
[edit] Handles
See main article: Door handle
Doors generally have at least one fixed handle, usually accompanied with a latch (see below). A typical "handle set" is composed of the exterior handle, escutcheon, an independent deadbolt, and the interior package (knob or lever). On some doors the latch is incorporated into a hinged handle that releases when pulled on.
See also:
Doorknob - A knob or lever on an axle that is rotated to release the bolt.
Crash bar
[edit] Locks
See main article: Lock
A lock is a device that prevents access by those without a key or combination, generally by preventing one or more latches from being operated. Often accompanied by an escutcheon. Some doors, particularly older ones, will have a keyhole accompanying the lock.
[edit] Fasteners
Most doors make use of one or more fasteners to hold the door closed. Typical or common fasteners include:
Latch - A device that allows one to fasten a door, but doesn't necessarily require an external handle
Bolt - A (nearly always) metal shaft usually internal to the door, attached by cleats or a specific form of bracket, that slides into the jamb to fasten a door.
Latchbolt - A bolt that has an angled surface which acts as a ramp to push the bolt in while the door is being closed. By the use of a latchbolt, a door can be closed without having to operate the handle.
Deadbolt - Deadbolts usually extend deeper into the frame and are not automatically retractable the way latchbolts are. They are typically manipulated with a lock on the outside and either a lock or a latch on the inside. Deadbolts are generally used for security purposes on external doors in case somebody tries to kick the door in or use a tool such as a crowbar or a hammer and screwdriver etc.
Strike plate - A plate with a hole in the middle made to receive a bolt. If the strike is for a latchbolt, it typically also includes a small ramped area to help the bolt move inward while the door is being closed. (Also known as just "strike") It's also available as electric strike which allows you to open the door even though the mechanical lock is locked.
[edit] Accessories
Numerous devices exist to serve specific purposes related to how a door should (or should not) be used. See:
Door closer - A device that closes an open door
Door damper - A hydraulic device employed to slow the door's closure
Door knocker
Door stop - used to prevent the door from opening too far or striking another object
Espagnolette (for a window)
Fingerplate
Letter box or mail slot
Peephole
