Small boxes, or blanket chest sides, the RTJ400 is capable of 16" in width.

Versatility is a key feature of the Leigh 16"(400mm) RTJ400 Jig. It makes 5 sizes of through dovetails at two different pitches, 3 sizes of single pass half-blind dovetails, and 4 sizes of box joints (finger joints). Perfect joint fit is guaranteed and repeatable with the patented Leigh elliptical guide bushing.
