Full Mortise Lock Measurement Diagram

Full Mortise Locksoffer dependability and smooth action. These precision made furniture locks are produced in Germany. Each is expertly engineered. Use on drawers and cabinet doors.

Full Mortise Locks are made to fit into a wood-pocket, in drawer top or door edge.  Once installed they are concealed with only selvedge and keyhole showing. Strikes not necessary and rarely used. Three key positions enable lock to secure drawers and left or right hand doors.  Use on applications where lock needs to be hidden.

Replacing Full Mortise Locks

Keyhole location measurement is critical.Replacement lock-keyhole-location must match location of keyhole in furniture.

To measure: easiest to measure old lock, if you have it:

  • Lock Keyhole Location: distance between selvedge-edge - where bolt shoots through, to lock pin. This measurement is known as the backset.
  • Furniture Keyhole Cutout Location: distance between furniture-edge to estimated location of lock pin in furniture keyhole.

Pure excellence!

Need a lock for an antique chest and they had the perfect fit!! Could not be happier- highly recommend!!! Will buy from again-

Well made, the tongue of the lock retracted flush with the body of the lock with nice quality machining to the body of the lock. It did not come with a keeper plate (which was noted) I had to use ones from locks I had and modify it to fit the purpose. Wouldn't be a bad idea to, maybe, sell them separately. The lock was for new work and a keeper plate was needed. I liked that it was a door lock that worked both left and right hand unlike most drawer/door locks where they are handed only one way. They worked fine for my situation.

Was a perfect fit. Would purchase items from Paxton again.

Cabinet Lock Set

Excellent quality and appearance. Had to expand the cutout for the larger size than the original.
