GN 820 horizontal acting 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.
Horizontal acting toggle clamps in the U-bar version with two flanged washers (Type M) can accommodate an application specific clamping screw. A spindle assembly with neoprene rubber tip is also included for Type MC.
Thanks to the shape of the toggle clamp assembly, a safe distance between the handle and the clamping bar is provided to prevent the operator's fingers from being pinched while opening the instrument.
Type O version can 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 GN 809 Clamp Mounts to hold the work piece in place.
For stainless steel version see GN 820-NI.
