Maximum stability: The optimized profile shape guarantees a higher build-up of clamping force in a shorter time while providing greater stability and safety. The solid forged fixed bracket with a molded pressure plate is tempered and galvanized, making it highly load-bearing and torsion-resistant. The forged sliding bracket, shaped like a U and made 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 workday. It can be easily and quickly swapped out. Smooth spindle: The surface-coated spindle with trapezoidal thread is particularly smooth-running and does not jam, allowing for even more efficient work.
