This router jig is one you can count on. Made from CFC core melamine, its light weight and provides a smooth, easy surface to run your router base on. Like our housing unit system, the jig clamps onto your desired location with the adjustment of an arm/fence on the back of the jig. Simply interchange the 1/4" steel shafts to prep for the mortise and or tabs of the pivot hardware. No need to remove and re-align jigs for your different depths of cuts. Contact us for more information of equipment and router bits to use when prepping for this pivot system.
