Description
Proudly made in the USA by Dubuque Clamp Works, these aluminum bar clamps are lightweight, extremely rigid, and easy to adjust. The heat-treated extruded aluminum bars measure 1-3/8 x 7/8in. and have side walls nearly 1/8in. thick for excellent resistance to bowing and twisting. The adjustable head has a spring clutch for easy adjustment along the notched bar, and the fixed head has a 1/2-in. diameter Acme-threaded screw and wing knob for final tightening. Because these clamps remain reliably straight under clamping force, you can clamp your workpiece against them to prevent misalignment.
