Sacrificial fences have never been so easy to hold. This product gives you the versatility to attach just about any sacrificial fence, re-saw fence, half fence or any other variety of fixtures to your fence without having the clamp interfere with your work. Simply drill a 3/8" hole in the top edge of each end of your sacrificial fence, tighten the clamp against your original fence and you are ready to cut. You can also use one clamp at any location along the fence as a stop block. It works great with table saws, router fences, band saws and more.
