Maximum stability: the optimized profile shape ensures a higher clamping force build-up 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, is made of forged alloy steel and guarantees maximum safety through linear force transmission, withstanding even the greatest 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.
