Maximum stability: The optimized profile shape ensures a higher clamping force development in a shorter time with 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, made from forged alloy steel guarantees maximum safety through linear force transmission and withstands even the greatest loads. You can rely on it at any time. 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.
