Shop Fox D2466 Aluminum Bar Clamp 36-Inch

From the Manufacturer Rigid torsion-box style bars allow these light aluminum bar clamps to maintain in-line clamping pressure without bending or twisting. Simple spring loaded detent action of the fixed jaw provides quick and secure adjustments and, since the sliding jaws wrap completely around the four-sided bar, there is no lifting or twisting of the jaw faces as pressure is applied. We think you'll agree, these are the best bar clamps around.
