Bench Dog Tools 10-038 Universal Fence Clamp
From the Manufacturer These compact, lightweight Fence Clamps allow you to secure a huge variety of shop-made auxiliary fences to your existing fences without having the clamp interfere with your work. The clamp arm simply fits into a 3/8-Inch hole in the top of the auxiliary fence, keeping it out of the way. That means no more clunky wood screws and C-clamps and no need to screw into your expensive fence! Works great for table saws, band saws, cutoff saws, router fences and more. Clamps can be used singly as stop blocks, or in pairs for sacrificial fences, half-fences, ripsaw fences, and a variety of other fixtures. One set of clamps will do it all. Includes 2 clamps.
