Information

GN 820 Horizontal acting toggle clamps work according to the toggle principle: lever and clamping bar move in the opposite direction.<BR>
<BR>
They require less space for the clamping action. In the clamped position the operating lever is in its horizontal position.<BR>
<BR>
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.
<BR>
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 Clamp Mounts to hold the work piece in place.
