A heavy-duty dual purpose clamp and spreader with a large gripping force. The tough ABS plastic jaws can be set at any position on the high-tensile steel bar. Single handed trigger operation releases the force, freeing the clamp jaw for adjustment. Tool-free head release allows the clamp to be quickly turned into a spreader. The cushion gripped jaw pads help protect work surfaces from marks, soft surfaces may need further protection due to the force of gripping power.
