The clamping mechanism ensures controlled, quick, and vibration-resistant clamping. 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 solid clamp arm, forged from a single piece with an integrated pressure plate, is heat-treated and galvanized, making it highly load-bearing and torsionally rigid. The sliding arm is serrated and forged from heat-treated steel, ensuring 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 releasing the clamp.
