Product Description

GN 820.1 Horizontal Clamp with Vertical Base

These GN 820.1 horizontal acting toggle clamps work according to the toggle principle: the 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. A special feature of this clamp is its low profile in clamping position. They are designed in such a way to avoid the operator's fingers being caught between the retracting clamping arm and the operating handle (safety distance).

Horizontal acting toggle clamps in the U bar version with two flanged washers (Type N) can accommodate an application specific clamping screw. A spindle assembly with neoprene rubber tip is also included for Type NC (GN708.1).

Type P 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 GN809 Clamp Mounts to hold the work piece in place.
