  • 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 Measurement Diagram


    Backset: distance between: selvedge-edge of lock to center-of-pin in keyhole. (see diagram)

    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


    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.

    If Using Brass Wood Screws

    Care is required when installing brass screws. While these screws are the best match for most antique hardware however they are not as strong as steel screws. The screw is easily damaged if the hole is not properly prepared.

    The best practice is to first drill a pilot hole. Use a drill bit slightly smaller than the overall width of the screw, including threads, to drill the hole. Then use a steel screw, the same size as brass screw, to “cut threads” in pilot hole, by screwing steel screw into and then out of hole.

    Cabinet lock

    Excellent replacement lock. Was better than original.

    replacement of antique hardware

    The web site is great. The short tutorials on the hardware, measurements, key shapes, and mechanisms is vital for a do it yourselfers like me. The site prevented me from making mistakes that usually plague my redo projects.

    Paxton a staple

    I have ordered from Paxton before the internet and they have been and still are a reliable source. Their detailed description takes the guessing out of ordering.

    Lock and Key

    These were the perfect match to work for our antique armoire we were restoring. We made a few adjustments but they worked out very well. We had thought we would originally try to find vintage ones to restore the armoire but it was impossible to find three to work for the doors. So we were very satisfied with the end results.
