A Hundred Jigs In One

The Router-Ease Guide is an American- made tool designed to meet the needs of both the weekend enthusiast and the professional. The Router-Ease Guide functions as a two- or four-sided adjustable jig/template. The Router-Ease Guide eliminates downtime used to design and makes jigs or templates for particular routing tasks. It can be set for cutting dadoes, stop dadoes, rabbets, hinge mortises, pocket mortises, fluting or sink cutouts on countertops. The Router-Ease Guide can even be used to cut dadoes on an angle such as the short, stopped dadoes used in louvered shutters or doors. Two innovations make this guide easy to use: the Gauge Block and the Dado Block. Both are included with the Route-Ease Guide and are used to quickly and accurately set the guide arms. The Dado Block is used with a 1/2-in. straight bit and the included subbase. The Gauge block is stepped to allow for the use of 1/2-in., 3/8-in., and 1/4-in. bits. Simply set the appropriate block along a guide arm, move the arm until the block touches your layout line and tighten the lock-down knob.
Available in three stock sizes and custom sizes.
