Latch

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.

Types of Latches

Deadlatch
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.
