Stainless Steel Heavy Duty Adjustable Tension Levers have proven to be ideal wherever parts have to be clamped in a confined space, or if a particular lever position is required. The threaded insert is connected with the hub via serrations which can be disengaged.
Pulling the lever upwards disengages the serrations, allowing it to be swivelled to the ideal clamping position. Upon releasing the lever, the serrations automatically re-engage.
