Ergonomy and design

The particular design of this knob follows rigorous ergonomic standards: five-lobe shape, blended radius, well proportioned rim height offer a natural, safe and comfortable grip, allowing the operator to obtain a strong clamping action. <BR>

Features and applications

Particularly suitable where the knob needs to turn freely to avoid that clamping may be accidentally affected.<BR>AISI 303 stainless steel, thanks to its high resistance to corrosion, allows the application of these knobs on machines and equipment in those sectors where laws or particular hygienic, climatic and environmental factors make it mandatory to use corrosion resistant materials.<BR>


Press the knob to engage the toothing and turn it. <BR>By releasing the knob the spring releases the toothing, thus the knob returns to the rest position.


Glass-fibre reinforced polyamide based (PA) technopolymer. Resistant to solvents, oils, greases and other chemical agents. Built-in zinc alloy toothed insert for coupling to the metal clamping element.
