Made of anodized aluminum, this clamp-mounting plate lets you add a work hold-down wherever you need it. For example, you can recess it into a bench top or leg, install it on a sawhorse, or incorporate it into a jig. The keyhole slot is designed to accept Kreg’s spring-loaded steel clamps (available separately), allowing 360° clamp rotation for best positioning or easy removal whenever you need an unobstructed work surface. The plate measures 3" × 4" × 1/4" thick, and comes with mounting hardware and instructions.
