Maximum stability: The optimized profile shape ensures a higher clamping force build-up in a shorter time while providing greater stability and safety. The one-piece forged fixed bracket with a molded pressure plate is heat-treated and galvanized, making it highly load-bearing and torsion-resistant. The forged sliding bracket, shaped like a U from forged alloy steel, guarantees maximum safety through linear force transmission and withstands even the greatest loads. You can always rely on it. Interchangeable pressure plate: The tool-free interchangeable pressure plate adds even more convenience to your daily work. It can be easily and quickly replaced. Smooth spindle: The surface-coated spindle with trapezoidal thread is particularly smooth-running and does not jam, allowing for even more efficient work.
