Elma (044-2120) Knob Nylon (Polyamide) Round with Indicator Line 10 mm

Elma (044-2120) – Nut Cover, With Indicator Line, 10mm

The Elma (044-2120) is a black, glossy nut cover accessory for Elma's Classic Collet knob range, sized to fit the 10mm knob diameter. It's designed with a "with line" (indicator line) marking style and made of polyamide, matching the resistant material used across the collet knob line. Unlike a standalone knob, this part conceals the collet tightening elements on knobs it's paired with — it's an accessory, not a shaft-mounted knob itself.
