INCRA I-Box Joint Jig

Box joints made easy on the table saw and router table. The new INCRA I-Box is the most advanced tool ever created for producing a stunning variety of box joints and finger joints. Its revolutionary design allows for faster setup, greater versatility, and enhanced user safety compared to traditional jigs. Despite its sophistication, it's easy to use, with a free online instructional video that covers everything from basic setup to advanced decorative joinery.

This versatile jig works on both table saws and router tables and is available to fit either 3/4" x 3/8" standard miter slots or Shopsmith machines. We also offer unique I-Box Combos and accessories to get you up and running quickly—box joint blades, tools for making wooden hinges, spare backer boards, and more.

The I-Box is a significant leap forward from conventional box joint methods—this single jig can be used on both your table saw and router table. Its dual pitch lead screw mechanics allow for easy micro-adjustment of joint tightness and offer a wide range of pin widths from 1/8" to 3/4". It can create perfectly fitting box joints using any width cutter within that range, working with lumber from 1/4" to 7/8" thick.

The benefits go far beyond the basics: I-Box-exclusive joints like the Center Keyed Box Joint allow for the creation of symmetrical patterns on any width lumber, giving you the flexibility to match existing project plans without needing to alter board widths as you would with traditional box joint jigs.

The Splined Box Joint is another unique INCRA decorative joint guaranteed to add a wow factor to your projects, and the I-Box can even be used to produce a limitless variety of classic dentil moldings!

Nothing showcases "craftsmanship" quite like solid wood hinges, and the I-Box can be used with the INCRA HingeCrafter to create wooden hinges in four different barrel diameters and in lengths up to 10". It also works with the metric HingeCrafter!

If you're looking to enhance your shop's joinery capabilities with a fast, versatile, and easy-to-use method for producing all types of box joints, the INCRA I-Box is exactly what you've been waiting for.
