Vertical clamp 291 R

Heavy duty, precision design 

These clamps are designed for both a high clamping force and a long service life. The control-lever weldment is made of carbon steel, heat-treated to 800–1000 MPa. The control-levers of the 291 and 293 models are made of cast steel. The fastening legs, draw rods and pivots are made of carbonitrided material and hardened to 48 HRC. The clamps are all blackened. The main intended application is with heavy-duty jigs for cutting or welding, for example in the automotive industry.
