GN312 Safety Hand Tension Lever, Push Engage
These safety tension levers are used on such applications where a thoughtless or accidental releasing or repositioning 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.
