What Is a Sash Lock?

A sash lock (or mortice sashlock) is a type of door lock fitted into a mortice (cut-out) in the door edge. It includes both a latch operated by a handle and a deadbolt operated by a key, making it more secure than a latch alone. Sash locks are commonly used on front doors, internal room doors, and gates.
