A common style residential latch.

A latch is a primary component of many locks. When activated, latches are positioned within a recess to prevent something from moving or opening. Latches are similar in function to bolts, but are instead angled or beveled. The bypass of latches in doors is called loiding.

Types of Latches

A latch with a beveled edge that is locked by end pressure.
Deadlocking Night Latch
A latch that uses repeated actions to lock, double lock, or unlock.
Mortise Deadlatch
A deadlatch that is installed within a door.
Narrow Stile Latch
A latch designed to automatically keep a door closed. Similar to a deadlatch, though not subject to end pressure.
