Horizontal Acting Toggle Clamps GN 820.4

Product description

Information

Horizontal acting toggle clamps GN 820.4 have a safety function whereby, during closing, a spring loaded safety hook latch ensures a secure locking connection. It prevents the inadvertent unlocking of the clamp due to vibrations or an accidental attempt of loosening / opening of the clamp. To open and release the clamp, pull up on the finger grip to disengage the safety hook latch mechanism (one hand operation).

They work according to the toggle principle: lever and clamping bar move in the opposite direction. They require less space for the clamping action.

Horizontal acting toggle clamps in the U-bar version with two flanged washers (Type NL) can accommodate an application specific spindle assembly. A spindle assembly with neoprene rubber tip is also included for Type NLC.

Type PL version can either be utilized by welding the clasp which can then accommodate an application specific hold-down fastener component.
