Adjustable Universal Fence Clamps 2-pack Ideal for Clamping Sub Fences to Table Saws and Can Be Used to Hold Jigs and Fixtures in Place When making auxiliary fences most of us have the issue of our clamps getting in the way of the cut or in our line of site. Not only can that be frustrating, that can also be very dangerous. With these new fully adjustable fence clamps, that problem all but disappears. The adjustable fence clamps won't interfere with your work and they can be used for many other shop made auxiliary fences if needed. The clamp pin will fit into a 3/8" hole that needs to be drilled into your auxiliary fence. Note: Your fence should be at least 3/4" thick to ensure that there is enough clearance for the 3/8" hole. When fully extended the clamp measures approximately 5-3/4" in clamping capacity, which means it will fit almost any size tablesaw fence. With these clamps you won't have to worry about using cumbersome C-clamps or wood screw clamps that honestly just get in the way. More importantly you don't have to drill screw holes into your factory or after market fence(s). The Adjustable Fence Clamps work great on tablesaw fences, router fences, re-saw fences for the bandsaw, and more. You can also use the clamps individually with a block of wood for a stop block and other jigs and fixtures. Each package comes with a set of two fully Adjustable Fence Clamps.
