                   On 9th May we advised that "Due to Trump's tariffs all Vernier prices are going up by 10% as new stock arrives so buy NOW". With the lower tariffs announced on the 12th May we can advise that all Vernier prices are only going up by 5% as new stock arrives. Gosh I hope there are no more changes of undies!!       Due to foreign exchange and freight costs many Molymod products will or have already increased in price.

IEC KNOB BLACK NOTCHED PLASTIC 35mm DIAMETER 6mm HOLE
IEC 35mm diameter black plastic knob with notched skirt to fit 6mm diameter shafts, will not fit 1/4" diameter shafts. Fitted with a hex grub screw that requires an Allen Key to tighten or remove.

A replacement for the knobs used on IEC instruments like their power supplies.

N.B.
A few years ago IEC changed the knobs they used from one that had a circular aluminium insert on top (also pictured) to this knob with no insert. The knobs are interchangeable on any 6mm shaft.

NOTE: This is a genuine IEC product.
We believe in supporting Australian industry and only sell genuine IEC products, we do NOT sell imported clones of IEC products.
