    Full Mortise Lock Diagram

    Before looking for a replacement it will be necessary to measure your lock.

    Please view diagram below to determine how to measure your lock.

    The backset measurement, is the most important measurement, must match precisely.

    Once the backset measurement is determined you can look at your various options.

    If potential substitutes have different lock-body or lock-plate measurements cabinet work may be necessary to fit the lock.

    FULL MORTISE INSTALLATION

    Determine desired location of lock

    Adjust position to allow for location of keyhole as it is often off center in lock

    Lock should be positioned in middle of wood thickness, providing a wood edge around selvedge

    Mark location of lock-selvedge on door or drawer edge

    Hold lock-selvedge, at desired location, on wood thickness and trace outline

    Inspect outline for accuracy , straighten lines where necessary

    Mortise Selvedge

    Lock-body

    Trace lock-body outline into selvedge-mortise at correct position

    Cut lock-body-mortise

    Mortise can be slightly off as selvedge will conceal lock-body once installed.

    Check lock with mortise, lock should sit in mortise with selvedge flush with wood surface

    Strikes are rarely use with reproduction full mortise locks. Traditionally a simple mortise was cut in the wood to accept the lock bolt.

    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

    Mount Lock

    Mount lock in a mortised- pocket in wood thickness/edge

    Selvedge edge should be level with top of drawer or edge of door

    Attach with wood screws

    For a finished appearance: mount an  escutcheon/keyhole plate, on furniture 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.
