With neither riser block nor adjusting required, the system allows a continuous adaptation of the clamping height whilst retaining the clamping force with the simple turn of the clamping key. Adaptable to all types of machine-tool tablles, electro-erosion machines and modular or press T-slot tables(model dependant). The clamps are "monobloc" types, which ensure stable, robust and rapid assembly for setting up and dismantling with a clamping force upto 50000N.
