Product description

Safety five-lobed knobs GN 5337.3 are best suited for applications where any unintended loosening of the knob may lead to accidents.

In non-operative mode, the lobe knob is not engaged with the tapped insert; i.e., the knob can be turned easily. Only after axial pushing of the knob does the knob engage with the insert, so that it may be tightened or loosened. After release, the serrations disengage by means of a spring.

The five lobe design is visually appealing and also gives the operator the means to achieve higher torque.

Resistant to solvents, oils, grease and other chemical agents.
