Looking for a durable, high-security lock for your home, office, or commercial space? A mortise lock offers unmatched strength and reliability, making it the top choice for residential and commercial doors. Designed to be embedded into the door itself, mortise locks provide enhanced protection against tampering and break-ins.

What is a Mortise Lock?

A mortise lock is a mechanical lock installed into a cut-out cavity (called a mortise) within the edge of the door. Unlike surface-mounted locks, mortise locks are hidden inside the door, giving a sleek appearance and strong structural integration. They're commonly used on wooden doors and metal doors, especially in high-traffic or high-security areas.

Key Components of a Mortise Lock:

• Lock Body: Main unit inserted into the door cavity

• Latchbolt: Holds the door closed when not locked

• Deadbolt: Extends for enhanced security when locked

• Strike Plate: Attached to the door frame to catch the latch or deadbolt

• Handle or Lever (optional): Some models include a handle for easier operation

How Does a Mortise Lock Work?

1. Installation

A mortise lock is fitted inside the door’s edge using precise cutting. It fits snugly within the mortised pocket and is secured with screws and faceplates.

2. Locking Mechanism

• The latchbolt keeps the door shut when the handle is released

• When locked, the deadbolt extends deep into the frame for maximum security
