Accessories on request
Ball and spring for clicking operation to be fitted in the assembly hole for knobs with diameter D ≥ 48 mm, available only for IZN.381 (see ball and spring MS.).
By adjusting the housing unit (unit made pass-through and threaded), facilitated by the presence of a pre-drilled hole in the top part of the knob, it is possible to use GN 615 ball and spring plungers (neutral execution) and GN 616 bolt spring plungers (knob with flange) to calibrate the pressure of the positioning element.
