Maximum stability: The optimized profile shape guarantees a higher clamping force build-up in a shorter time, while providing greater stability and safety. The solid 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 in a U-form from forged alloy steel, ensures maximum safety through direct force transmission and withstands even the heaviest loads. You can always rely on it. Replaceable pressure plate: The tool-free replaceable pressure plate adds even more convenience to your daily work. It can be exchanged very easily and quickly. Smooth spindle: The surface-coated spindle with trapezoidal thread is particularly smooth-running and does not jam, allowing for even more efficient work.
