Adjustable clamping levers GN 6337.3 have proven to be ideal wherever parts have to be clamped in a confined space or a particular lever position is required. The insertis connected with the lever via serrations in the ball bore which can be disengaged.
Pushing the lever downward disengages the serrations, and the lever can be swivelled to the best clamping position.
Engagement is achieved by releasing the lever.
