The Box Joint Jig is the easiest way to make box joints because the work piece moves over the jig. That means there's less chance for error and better results than jigs that require moving both the jig and the work piece for each cut! This box joint jig is compatible with a miter gauge. It can be used with most table saws and router tables with standard slots. Made of high quality aluminum alloy, the box joint jig is wear resistant and rustproof.
