IRWIN 225101 100 Series 1-Inch C-Clamp
The Irwin Quick-Grip 1-Inch C-Clamp has a long handle to prevent skinned knuckles while making it easier to apply torque. The double-threaded screw thread also cuts down on the time needed to apply pressure, and reduces drift due to screw deflection. The large swivel pad protects against damage to work surfaces and improves stability. Irwin backs its clamp with a lifetime warranty.
