York 3 Lever Mortice Deadlocks

3 Lever Key Deadlocks for Internal Doors

The York Security 3 lever deadlock is a key-only mortice lock for internal doors that need to be secured but do not need a latch, such as store rooms, cupboards, plant rooms and internal doors in offices or shared houses. It is made by M.Marcus and finished to coordinate with its door furniture.

Internal or external?

A 3 lever lock is designed for internal security. For front and back doors, choose a York BS3621 5 lever deadlock instead, which is the standard most insurers require.
