This Door Mortise Lock Jig Kit is a portable door lock installation solution designed for carpenters and DIYers working on wooden doors. The kit includes a lengthened, widened anti-slip mat (45×34 cm), a removable sliding bearing between the positioning ring and bearing seat to reduce friction, and a fixed bottom screw to lock the guide rail for steady, accurate mortising. Vertical guides feature height and depth stops to prevent overrun during cutting.
The jig supports wooden door thicknesses from 25 to 90 mm and handles a maximum grooving depth of 140 mm and grooving length of 240 mm, covering common lock installation needs. The package contains 3 M10 tungsten steel alloy cutters (18 mm, 22 mm, 25 mm), 2 spanners, a ruler, a wood chisel and a plastic suitcase. At a gross weight of 11 lb (5 kg), the set is lightweight enough for easy handling and transport while offering durable cutters suited for wooden door work.
