Mortice Locks

Yale offer a comprehensive range of mortice locks for timber doors, including British Standard 5 lever locks which offer the maximum level of security for external timber doors.   Mortice locks are installed inside the door, and there are a range of sizes, security levels and functions which you need to consider before you make your purchase. A Deadlock features a bolt which is operated by a key, and is often used in conjunction with a nightlatch. A Sashlock features a bolt and latch and is for use with door handles. To check the size of your existing lock without removing it from the door measure the distance from the keyhole to the edge of the door. If the distance is 45mm you will need a 64mm/2.5" mortice lock, If the distance is 57mm you will need a 76mm/3" mortice lock.
