Product description


Safety star knobs GN 5337.3 are most suitable for applications where an accidental or inconsiderate loosening or adjusting of the knob may lead to accidents.

In non-operative condition, the star knob is not linked with the threaded bushing, i.e. the knob can be turned easily.

Only after axial pushing of the star knob, the two serrations get engaged so that the knob can be untightened resp. tightened.

Atfer releasing, the two serrations are disengaged by a spring.
