The VB.839 three-arm knobs, previously awarded IF Design Award 2019 and VTD torque-control knob shave both been awarded the Red Dot Design Award in the Product Design category. The jury recognized the unique design of the BVB.839 three-arm knob: an ideal overlap of two triangles rotated by an angle of 8 °.
The particular ergonomic shape allows a more direct application of the tightening torque by the operator, resulting in maximum comfort and safety in clamping operations. A technopolymer body with an over moulded polyamide based technopolymer, chemically bonded, offers a semi-glossy finish.
The innovative double injection moulding process allows to obtain knobs with high resistance to stresses, impacts and with a perfectly smooth surface. The three-light lobe design of the VTD torque limiting knob fits perfectly to the operator’s hand thanks to its ergonomics A slight tapering increases the grip, maximizing the effort of the hand in rotating the knob.
In addition to its special design, the knob also features an innovative functionality: an internal system limits the applied tightening torque during clamping preserving the application surface. The ability to innovate and renew is once again winning in Elesa+Ganter!
