    Half Mortise Box Lock Measurement Diagram

    Brass Box Locks are heavy duty, half mortise style for large chests with lift lids. Excellent quality. Each is crafted of brass in England.  Use on large tool boxes and blanket chests.

    When installing lock must be mortised into wood. Lock strike is attached underneath lid. When closing lid curved prongs of strike drop down into lock selvedge. Once installed the lock plate will create a smooth continuous surface on the interior of chest. Exterior of chest will only display keyhole.

    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.

    Found a chest lock that fit

    After alot of searching, I found a chest lock that fit my blanket chest. Yes, the new lock body was rectangular, so I changed the half mortise from trapezoidal to rectangular. Most importantly the key hole distance to chest's edge was selectable and correctly chosen. The new lock had to be adjusted slightly to better fit the vintage footprint, but all in all a great match.

    Excellent lock for a chest - the biggest and best I could find that delivered to the UK.

    Perfect Replacement

    I bought this lock as a replacement for a restoration of my grandfather's old wooden tool chest. It was an easy installation, looks good, and works perfectly. This is an excellent product that I would highly recommend.

    I was frustrated not being able to find what I thought should be a readily available lock for the tool chest I made. I discovered the Paxton site after 2 wrong choices and too much search time. The lock was perfect. The perfect size; made in England, not china and priced well.

    Beautiful Lock

    Perfect lock for my grandfather's blanket chest!
