||Elesa® original design
technopolymer plastic Ergostyle® knurled knobs.
When used as a push-pull button, the thumb rests naturally on
the concave front surface, making it easier to grip the knob.
The slight knurling on the rim of the knob makes tightening
or clamping operations easier.
Resistant to solvents, oils, grease and other chemical agents.
