Irwin 2025101 C-Clamp, 10 lb Clamping, 1-1/2 in Max Opening Size, 1-1/2 in D Throat, Steel Body, Blue Body

Larger handle on this C-clamp makes it easier to apply torque for more clamping pressure with less hand fatigue, double-threaded screw reduces screw deflection and drift for faster clamping and allows you to apply 50% more clamping force than with most clamps for woodworkers, carpenters, welders, builders or do-it-yourselfers, suitable for general clamping needs, larger swivel pad reduces marring on work surface and increases stability.
