Rockler has updated its router table box joint jig which features a larger, designed backer sled made from reinforced nylon and with dedicated spots for clamping the workpiece. The sled now incorporates the indexing key for positioning the workpiece during each cut, and the jig comes with three interchangeable brass indexing keys for 1/4, 3/8, and 1/2 inch box joints. It features upgraded easy-to-grip five-star knobs and comes with a replaceable MDF sacrificial fence for mounting to the backer sled. Priced at $79.99, the jig has an MDF base with a smooth melamine surface and precision-machined slots that keep the sled from traveling too far into the bit.
