Additional information

Clamping element

Black-oxide steel threaded stud with return spring and toothed element for coupling to the lever body.

Features and applications

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.<BR>The lever in its rest position is not connected with the internal spindle and can be rotated unhindered.<BR>The tension lever engages in the serration only after pushing it down, thus allowing clamping or unclamping.<BR>The "freewheel" position is re-established as soon as the handle is released.

Handle

Plastic ball knob DIN 319, black colour.

Material

Black-oxide steel.

Standard executions available

– Execution <STRONG>E</STRONG>: angled lever.<BR>- Execution <STRONG>D</STRONG>: straight lever.
