BESSEY anti-slip system - the set screw is molded into the sliding arm and interlocks with the serrated rail to prevent sliding
Corrugated malleable cast iron fixed jaw and sliding arm generate powerful, rigid clamping; top jaw press fitted to rail - no mechanical fasteners to loosen
High-quality profiled steel rail acts as a reliable reinforcement against torsional forces, while the serration on 6 faces additionally prevents the clamp from slipping
