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 grooves, 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 provides reliable reinforcement against torsional forces. The BESSEY hollow profile rail, produced in-house, 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, allowing for quick and easy replacement.
