Surface Lock Information


Surface Locks are used on furniture and cabinet doors.
Easy to install: No mortising is required as lock mounts directly to the inside of the cabinet door.
  • A strike is rarely used as it can impede the bolt from smoothly extending behind face frame or door stile.
  • Our surface locks are reversible meaning they will work both right and left hand doors.
  • Please note: these locks are visible when looking into a glass curio or china closet door. If preferred a half mortise or full mortise lock will provide a less visible alternative.
  • Surface Lock Measurements
    When measuring consider:
  • Backset: distance between: selvedge-edge of lock to center-of-pin in keyhole. (see diagram on right)
  • When replacing locks: the backset is most crucial as it must match cutout in furniture for lock to line up correctly with existing keyhole
  • Be sure overall size of Lock-Plate will fit onto door stile/face frame
  • When installing consider:
    Determine desired location of lock
  • Position of lock must allow for bolt to extend behind face frame of cabinet. A minimum of ¼" is necessary to secure door when locked.
  • Ideally edge of lock should line up with edge of door
  • If keyhole already exists in door, make sure lock-keyhole lines up with cabinet-keyhole
  • Keyhole Placement
  • Measure distance from top of lock-plate to center of key pin
  • Measure distance from side of lock-plate to center of key pin
  • With these two measurements locate keyhole on furniture front, make sure key pin is aligned with keyhole location
  • Drill small pilot hole at key pin location, hold lock in position and check to make sure hole lines up with key pin
  • Drill hole larger to accommodate key barrel
  • Cut remaining portion of keyhole with a small keyhole saw
  • Mark location of lock on door interior
  • Insert key from front through door into lock
  • With key in position, hold lock at desired location on back of door and mark screw holes
  • Drill small pilot holes for screws
  • Mount Lock
  • Mount lock and attach with wood screws
  • For a finished appearance: mount an escutcheon/keyhole plate, on door front.
