This cabinet hardware jig is a precision tool designed for consistent and accurate drilling of mounting holes in cabinetry and furniture. It features dual metric and imperial scales calibrated to 1mm. or 0.1 in. accuracy, with drill guides fitted with pointers for visual alignment. Horizontal and vertical rulers maintain perpendicularity within 1 part per thousand, ensuring square hole placement. Constructed from oxidized aluminum alloy, it resists rust and wear while remaining lightweight. The jig breaks down into 3-compact components a straight ruler with integrated drill guides, an L-shaped ruler, and 2-4mm. drill bits enabling easy storage and transport. Both drill guides adjust freely across an 8 cm range, allowing flexible spacing control via a central nut for vertical distance calibration. Soft PVC pads on the back prevent surface marring during use. It supports installation of handles, pulls, and knobs on drawers, cabinet doors, and panels without requiring additional measuring tools or marking.
