Product Description

GN820 Horizontal Clamp, Steel, Zinc Plated, Horizontal Base

These 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 for this horizontal 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 M) can accommodate an application specific clamping screw. A spindle assembly with neoprene rubber tip is also included for Type MC (GN708.1).

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

Stepped side washers and clamping bolt retainers are included.

Compatible with GN708.1 clamping bolt, with rubber tip.
