The clamping mechanism ensures controlled, quick, and vibration-resistant tightening. The particularly wear-resistant eccentric guarantees a long service life. The optimized profile shape allows for a uniform build-up of clamping force with greater power reserves, especially when fully utilizing the clamping range. The one-piece forged fixed arm with a formed pressure plate is heat-treated and galvanized, making it highly load-bearing and torsionally rigid. The sliding arm is serrated and forged from alloy steel, which ensures an extremely long lifespan. The powder-coated clamping lever is designed for optimal ergonomics. The plastic-coated release lever with slip protection provides a secure grip when loosening the clamp.
