General information
Features and applications
Suitable where it is necessary to prevent the loss of the knob.
The elastic retaining ring, housed in the groove of the knob can turn freely. The coiled ring connects the elastic retaining ring to the chain.
The three-lobe shape with large recesses is particularly ergonomic also for smaller knobs, ensuring an effective grip even with work gloves.
The design without rear cavities, generally adopted for reducing thickness, prevents unhealthy residues from depositing, ensuring easy cleaning. Particularly suitable for applications on machines and equipment whose parts must be frequently cleaned by using water jets or steam.
