Information

Toggle clamps GN 820.3 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.

Toggle clamps in the with forked clamping arm, with two flanged washers (type ML) can accommodate an application specific clamping screw. A clamping screw with neoprene rubber tip is also included for type MLC.

Toggle clamps in the type OL 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 holders for clamping screws to hold the work piece in place.

Toggle clamps in the U-bar version with two flanged washers (Type UL) can accommodate an application specific clamping screw. A clamping screw with neoprene rubber tip is also included for type ULC.
