Information

GN 820 Toggle clamps work according to the toggle principle: lever and clamping bar move in the opposite direction.

They require less space for the clamping action. In the clamped position the operating lever is in its horizontal position.

Toggle clamps in the U-bar version with two flanged washers (type M) can accommodate an application specific clamping screw. A clamping screw with neoprene rubber tipis also included for type MC.

Toggle clamps in the type O version can either be utilized by welding the clasp which can then accommodate an application specific hold-down fastener component, or by utilizing the bar in conjunction with the GN 809 holders for clamping screws to hold the work piece in place.
