Also know as "Trend Lock Jig for mortice locks and latches" it has the benefit of being able to adjust infinitely within its range of up to 250mm long and 16mm wide to cover any lock body and faceplate, eliminating any problems in fitting obscure locks and latches into doors. For general use with popular standard locks, a pair of quick setting blocks are supplied to quickly centre the jig on the door edge for 16mm and 19mm lock width and 22.5mm and 25.4mm face plate widths. Adjustable sliding inserts quickly set the widths for any lock for fast and accurate routing with a plunge router. Engraved lines on the jig ensure quick and easy set up for the lock size and door widths, with the wide, full length clamping bar ensuring the jig clamps to the door securely. With its infinite adjustability, it lends itself well to experimenting with other guidebushes and straight cutters for general morticing.
