Simply position the guide fingers to the pattern you want, and guide your router around the fingers to rout the joint you choose. No need to dimension the lumber to fit your jig! The D4R can handle joinery up to 24” in length and on boards up to 1-1/4” thick! Create flawless Dovetails and Box Joints with endless variations! No other Jig on the market can offer you so much joinery capability!

Adjusting the fit of your joints couldn't be any easier. When cutting half blind dovetails, you will lower or raise the bit to create a tighter or looser fit. When cutting box joints/finger joints, the included Leigh Elliptical guide bushing is turned clockwise or counterclockwise for a tighter or looser fit.

The D4R is both strong and portable. A true 1 piece CNC Machined aluminum jig body is the heart of the system. Cast metal end housings are used to secure the jig to mounting board or workbench. Boards are held securely with the built in cam action clamps against a non-marring textured clamping surface. Both rear and front stops are machined into the jig. Plus the rear stops are undercut for rabbeted half blind drawer fronts. All of this comes with a 5 year manufacturer's warranty!

If you are looking to get the very most out of your Leigh D4R Pro, consider adding the AC-D24 Kit. The foundation of this kit is the Vacuum and Router Support. Unparalleled dust control is achieved by attaching the VRS to your jig. The vacuum chute is trapped under the router, right where the cutting is happening and travels effortless along the jig as you move your router. This can easily adapt to most small vacuums as well as large built in vacuums on the market with the standard adaptors to fit hoses from 1” - 2-1/2”. Along with this AC-D24 Kit comes the Premium Leigh 13 piece Router Bit Set. 11 Dovetail bits, 5/8 Guide Bushing and a 1/2"-8mm collet reducer are all included in the wooden storage case. Each of these carbide tipped router bits are Swedish made and honed with a 600 grit diamond wheel to yield smooth and efficient routing.
