Adjustable tension levers GN 212.3 have proved to be ideal whenever parts have to be clamped in a confined space or a particular lever position is re-quired. The threaded insert is connected with the hub via serrations which can be disengaged. Pulling the lever, disengages the serrations and allowing it to be swivelled to the ideal clamping posi-tion. On releasing the lever it will automatically re-engage.
