Information

Toggle clamps GN 812.1 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.

They can be mounted in two planes via the dual flanged mounting base and require less space for the clamping action.

Toggle clamps with forked clamping arm, with two flanged washers (type AVF) can accommodate an application specific clamping screw. A clamping screw with neoprene rubber tip is also included for type CVF.

The clamps in the type EVF 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.
