The overall height of Stainless Steel-Flat tension levers GN 125.5 is reduced to a minimum. As all other adjustable levers, they are ideal whenever parts have to be clamped in a confined space, or a particular lever position is required. The threaded insert is connected with the hub via serrations which can be disengaged. Pulling the lever, disengages the serrations and the lever can be swivelled to the ideal clamping position. On releasing the lever it will automatically re-engage.
