These straight edge clamping guides are ideal for all types of woodworking, cabinet making, carpentry and D.I.Y. applications. Designed for circular saws, jig saws and routers, they are built with an aircraft grade extruded aluminum body for straight accurate cuts and rigid clamping. Easily clamp and cut everything from dimensional lumber to large flat sheets. Clamping pads have an exclusive swivel head that allows clamping up to 22-1/2 either left or right, so you can make angled cuts without the need for extra clamps to hold the edge guide in position. The large over-sized clamping handle allows for increased clamping pressure, while the soft-grip rubberized clamping pad insures that the material is firmly held in place without marring the work.
