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 an integrated pressure plate is tempered and galvanized, making it highly load-bearing and torsion-resistant. The U-shaped sliding bracket made of forged alloy steel guarantees maximum safety through linear force transmission and withstands even the greatest loads. You can rely on it at any time. The tool-free interchangeable pressure plate adds even more convenience to your daily work. It can be easily and quickly replaced. The surface-coated spindle with trapezoidal thread is particularly smooth-running and does not jam, allowing for even more efficient work.
