What are mortise locks?

Mortise locks are a type of locking mechanism that is installed within a pocket, or mortise, cut into the edge of a door. They typically consist of a lock body, which houses the locking mechanism, and a deadbolt or latch that secures the door when closed. Mortise locks are known for their durability and strength, making them a popular choice for commercial and high-security residential applications. They often require professional installation due to the precise cutting needed for the mortise.
