The VB.839 three-arm knob provides a direct torque transmission. With its form characterised by two overlapping triangles shifted by an angle of eight degrees, it ensures a safe and comfortable grip. By using smooth surfaces and dispensing with cavities, dirt deposits are largely avoided, simplifying the cleaning of the thermoplastic knob. The centre cover cap is available in a variety of colours so that the knob may be adapted, in terms of appearance, to different environments.
