What is a Mortice Lock?

A mortice lock is named for the way it is installed within a door rather than its operation. It fits into a recess cut into the leading edge of the door, providing a concealed and robust security solution. The front face of the lock is the only visible part when the door is open, offering a sleek and unobtrusive appearance.


Sash Locks: Combining Security and Convenience

A sash lock is a type of mortice lock that combines a bevelled latch, door handles or doorknobs, and a key-operated deadbolt. This combination ensures both convenience and enhanced security, allowing you to easily lock and unlock the door while providing a strong defense against unauthorised access.


Deadlock Mortice Locks: Reliable Key-Operated Security

Deadlock mortice locks operate solely with a key. When the key is turned, it throws the deadbolt into the door frame, creating a sturdy and reliable locking mechanism. Some mortice locks also integrate a cylinder lock for additional security.


The British Standard Kitemark: A Symbol of Quality

For a mortice lock to meet British Standard (BS3621) requirements, it must include at least five levers, and the screws fixing the lock to the door must not be accessible when the door is closed. Additionally, the mortice lock must be protected by a toughened Anti-Drill hard plate. Insurance-rated and approved mortice locks display the prestigious British Standard Kitemark, a mark of superior quality and security.


Advanced Security Features

Some mortice locks go beyond standard security by incorporating features like anti-pick levers (known as false gates), a curtain to protect the keyway from picking attacks, and hardened steel pins through the bolt. These enhancements fortify the lock against tampering and unauthorised entry.


Diverse Finishes and Applications

5 Lever Mortice locks typically come with 2 or 3 keys and are available in finishes like brass, satin chrome, and chrome. These locks blend seamlessly with various door styles and are commonly used on wooden doors in both residential and commercial properties.
