Toggle clamps GN 810 work according to the toggle principle: lever and clamping bar move in the same direction. In the clamped position the operating lever is in its vertical position. Toggle clamps in the U-bar version with two flanged washers (type A) can accommodate an application specific clamping screw. A clamping screw with neoprene rubber tip is also included for Type C. Toggle clamps in type E can be adapted to special requirements by welding with the supplied clasp.
