Yale Mortise lock 5140/22, left/right

The Yale 5140/22 mortice lock is a mechanical cylinder lock. Featuring a reversible latch bolt, you can easily adapt it for left or right-handed doors. An integrated latch lever lets you operate the latch bolt with a key, not just the handle. The lock is ready for installation with two-part rose furniture or security escutcheons. Locking is secured by a double-throw deadbolt.

Flexible installation and key control

The Yale 5140/22 lock adapts to your door. It features a reversible left/right latch bolt, which you simply turn according to whether your door is left or right-handed. Thanks to the integrated latch lever, you can operate the latch bolt not only with the handle, but also by turning the key in the cylinder.

Compatibility and mounting dimensions

Correct installation depends on key mounting dimensions. The lock features 90mm centres (the distance between the spindle hole centre and the keyhole centre). The backset, which is the distance from the forend of the lock to the keyhole centre, measures 50.5mm. The forend of the lock is 22mm wide. The lock is ready for installation with two-part rose furniture and is also compatible with security escutcheons requiring a 9mm diameter hole.
