To get right to the point, the INCRA I-Box is the most advanced tool ever produced for creating a stunning variety of box joints & finger joints. Its revolutionary design allows faster setup, greater versatility, and improved user safety compared to traditional jigs. At the same time, it's easy to use and the online instructions covers everything from basic setup to advanced decorative joinery.

This versatile design works on both table saws and router tables, and it's available to fit either 3/4"x3/8" standard miter slots or Shopsmith machines (use the selector above to choose the version). We also offer unique I-Box Combos and accessories
to get you up and running fast - box joint blades, gear for making wooden hinges, spare backer boards and more.

The I-Box is an evolutionary leap forward from conventional box joint methods - this single jig can be used on both your table saw and your router table, and the I-Box's dual-pitch lead screw mechanics easily micro-adjust joint tightness and provide a whopping 1/8" - 3/4" range of pin widths. It's capable of making good fitting box joints using any width cutter within that range in lumber from 1/4" to 7/8" thick.
INCRA I-Box-exclusive box joints like the Center Keyed Box Joint can be used to produce symmetric patterns on a wider variety of lumber widths than traditional jigs, making it easier to adapt box joints to existing project plans. Taking the Center Keyed joint a step further, the Splined Box Joint is yet another INCRA-only decorative joint that's guaranteed to add wow-factor to your projects.

As a bonus, the I-Box can even be used to produce classic dentil mouldings! Altering the spacing between cuts and height of the cutter lets you change the moulding's proportions to create a nearly infinite variety.

Nothing says "craftsmanship" like adding solid wood hinges to your projects, and the I-Box can be used in conjunction with the INCRA HingeCrafter to produce wooden hinges in four different barrel diameters and in lengths up to 10". Works with the metric HingeCrafter, too!

The INCRA I-Box is packed with innovative features:
Use it on your table saw or router table to cut great looking box joints with a stacking-type dado blade, dedicated box joint blade set, or straight router bits

Reversible design works on either side of the cutter

Exclusive dual-pitch lead screw mechanism for fast micro-adjusting and a broad 1/8" to 3/4" range of pin widths cut into lumber from 1/4" to 7/8" thick

Works alongside the INCRA HingeCrafter to produce solid wood hinges

Front and rear blade guards; front guard also stabilizes boards vertically and is adjustable for 1/4" to 7/8" lumber thicknesses for box joints or even thicker for other applications

The wide fence allows clamping lumber securely into position while cutting much better than hand-held boards, especially when joining small or large lumber (hand screw clamp not included)

Reversible & reusable MDF sub fence dramatically reduces or eliminates tearout

Exclusive INCRA GlideLOCK miter bar fits standard 3/4" x 3/8" miter slot with a 0.740" - 0.762" width adjustment range or is available in a version for Shopsmith machines (note: Shopsmith version will not fit the Shopsmith 10ER ). Miter bar position adjustable up to 6-7/8" away from saw blades (edge of blade to center of miter slot) or up to 7-1/8" from routers (center of
collet to center of miter slot).

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