Whether youâ??re installing one new knob or dozens of larger pulls - from 1 3/4 in. to 12 in. center to center - the Cabinet Hardware Jig Pro is the go-to choice for ensuring professional-quality accuracy and consistency every time. A movable end stop and built-in measuring scales (with imperial and metric markings) make it easy to position knobs and pulls precisely. Plus, the Cabinet Hardware Jig features movable, hardened-steel drill guides that lock in place to align with common hole-spacing measurements for cabinet knobs and larger pulls. The guides make it simple to drill straight, accurately positioned holes. This jig works with almost any style of knob or pull, too, making it exceptionally versatile.
