  • Full Mortise Locks   are precision made for furniture and cabinetry. Made in Germany these full mortise locks are expertly engineered. Each is well made offering dependability and smooth action. 

    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. 


    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.

    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.
