Frequently Asked Questions

What size box joints can this jig cut?

It cuts any box joint between 1/8" and 13/16" wide and up to 1-5/8" deep. See more router jigs and guides.

Does this jig work on a table saw or a router table?

Both. The jig is designed to make box joints on either a table saw or a router table, so you can use whichever machine you prefer.

What is included with the jig?

It includes a 24" aluminum Ultra Track with a bit/blade cutout, replaceable sub-fences, and adjustable pins. A miter gauge is not included.

Does it attach to my existing miter gauge?

Yes. The jig attaches to any miter gauge, though the miter gauge itself is not included.

How does the jig keep joints air-tight?

The sacrificial face plates create a zero-clearance cut matched to your blade or bit width, and adjustable pins prevent part slippage, so the fingers stay precisely spaced for tight-fitting joints.

What blade works best with this jig?

Flat-top-grind saw blades produce the crisp, flat-bottomed cuts ideal for box joints. Browse related saw blades & accessories.

Does the jig come with a guarantee?

Yes. It carries a lifetime guarantee against defects in material or workmanship.

What are the sacrificial face plates for?

They let you cut a fresh zero-clearance opening for each blade or bit width you use, which is what produces clean, tight box joints. Their color and material may vary.

Can I use it with router bits as well as saw blades?

Yes. On a router table the Ultra Track's cutout accommodates a bit, so you can cut box joints with joinery router bits as well as on the table saw.
