This Adjustable Lock Jig is made of 12mm thick High Pressure Laminate, dimensionally stable and with a lifetime guarantee never to warp. It is fully adjustable for lock faceplates up to 175mm in length. The jig includes interchangeable templates to cut mortice and faceplate recesses for the most popular door sash, mortice and deadlock sizes: two faceplate templates for 25.4mm(1") and 22.5mm(7/8") wide lock plates and templates for 19mm(3/4") and 16mm(5/8") wide lock bodies. These interchangeable templates have keyhole slots for quick and easy template changing.

Set-up is easy, you just need to mark the centre line of the door and the centre line for the lock. The mortice will be square to the door ensuring the parts are square and making it easier to fit the handles. It is suitable for doors up to 58mm(2.1/4") thick. You will require a 1/2" router with a 12.7mm(1/2") straight cutter (long reach if possible) and a 16mm guide bush. In addition, two clamps to hold the jig in place and a screwdriver to adjust the settings.
