For maximum safety when clamping from an extension of 80 mm, the integrated BESSEY slip protection ensures stability. A threaded pin in the sliding arm engages with the rail's ribbing, effectively preventing the clamp from loosening or slipping. Both the upper and lower parts are made from high-quality ductile cast iron and reinforced with ribs. The powder coating protects against corrosion, and the characteristic ribbed profile serves as a reliable reinforcement against torsional forces. The BESSEY hollow profile rail is specifically optimized for clamps. The six-fold ribbing additionally prevents the clamp from slipping. The tool-free interchangeable pressure plate adds even more convenience to your daily work. It can be easily and quickly replaced.
