Precision Door Latch Routing Kit

This door lock installation kit measures 79 mm (3 in) in length and 165 mm (6.5 in) in height, with a compact, rigid frame engineered for durability and repeat use in professional workshops and on-site construction. It is designed specifically to guide accurate marking, scoring, and chiseling of recesses for standard door latch and strike plate hardware. The structured layout ensures consistent transfer of measurements directly onto door surfaces—minimising manual measurement error and reducing rework. Ideal for carpenters, joiners, and DIY installers preparing interior or exterior doors for mortise lock fitting.
