Deadlatches

A deadlatch is a type of door lock mechanism that incorporates a spring-loaded latch, which is designed to automatically secure the door when it closes. Unlike a standard latch, a deadlatch has a built-in locking feature that prevents the latch from being retracted without the use of a key or thumb turn.

The primary purpose of a deadlatch is to enhance door security by preventing the latch from being manipulated or "jimmied" open with tools like credit cards. This makes it an effective choice for residential and commercial doors, offering a balance of convenience and protection. Deadlatches are commonly used in conjunction with other locking systems, such as deadbolts, to provide layered security.
