Leigh RTJ400 Router Table Dovetail Jig

The Leigh RTJ400 is purpose-built for router tables, making it easy to cut precise dovetails and box joints in materials up to 15-1/2" wide. Compatible with most 1/2" routers and standard router tables*, it integrates seamlessly into nearly any woodworking shop.

Unlike fixed-template jigs that are limited to a single joint size, the RTJ400 creates five sizes of through dovetails at two pitches, three sizes of single-pass half-blind dovetails, and four sizes of box (finger) joints—all with a single jig.

Whether you're building drawers, cabinets, boxes, or fine furniture, the RTJ400 delivers clean, accurate joinery with an efficient setup. Through dovetails can be cut in either wide- or close-spaced patterns for a traditional hand-cut appearance, while the unique clamping system allows both boards to be routed simultaneously for fast, precise half-blind dovetails.

The RTJ400 also produces four sizes of strong, symmetrical box joints—3/4", 3/8", 3/16", and 3/32"—and can easily join boards of different thicknesses, making it ideal for drawer construction and a wide variety of woodworking projects.

Workpieces are securely held against the jig's textured, non-marring clamping surface with the included cam-action speed clamps. Easily adjust these clamps to material thickness with one hand. Adjustable injection-molded side stops provide accurate board positioning and have a built in offset for half-blind dovetails and even allow for rabbeted drawer fronts.

Includes four 1/2" shank router bits.

*Note: A 1-3/8" diameter insert ring for your router table is needed to fit the RTJ400 e-Bush guide bushing. Check with your router table or router plate manufacturer to find out what adaptation, if any, is required.
