Safety tension levers GN 312 are used on such "applications where a thoughtless or mistaken releasing or re-positioning of the tension lever could lead to an accident.

The lever in its rest position is not connected with the internal spindle and can be rotated unhindered.

The tension lever engages in the serration only after pushing it down, thus allowing clamping or unclamping.

The 'freewheel' position is re-established as soon as the handle is released.
