4555K Box Joint Jig with Upgrade Kit

We've combined our popular Box Joint jig and Upgrade kit.

This jig is the easiest way to make box joints because the work moves over the jig. That means there's less chance for error and better results than jigs that require moving both the jig & the work for each cut. Check out the 4553 Upgrade Kit, which is a popular accessory for the 4555 Box Joint Jig.

• Cuts any box joint between 1/8" to 13/16".
• Includes a 24" aluminum Ultra Track with bit/blade cutout and replaceable MDF sub-fences.
• Adjustable aluminum pins prevent part slippage.
• Attaches to any miter gauge, miter gauge not included.

The Box Joint Jig Upgrade Kit adds additional safety, convenience and ease of use features to the 4555 Box Joint Jig.  

• Includes our 4555D five piece Setup Jigs for quick and easy setups of 1/4", 3/8", 1/2", 5/8" & 3/4" joints.
• Includes two adjustable Work Platforms that provide a safe and stable surface for the part to rest on. Made of slick 1/4" thick HDPE (color may be black or white), they attach to the underside of the 24" Ultra Track from the 4555 and eliminate friction between your saw or router table and the bottom of your workpiece. Also includes an Adapter Head for attachment to your miter gauge so you don't have to make your own.
• Includes a Stop that attaches to the back of the 24" Ultra Track. This indexes against a side of the Adapter Head to help fine tune the joint size. Also includes a bit/blade Shield that attaches to the top of the 24" Ultra Track and projects out the back where the bit/blade exits.
