Wiedemann Rotary Knob for ECM – Olive Wood
Wood under your hand as you open the valve – warm, grained, and each piece unique.
The Wiedemann rotary knob made of olive wood with a 7mm internal square drive made of stainless steel, for ECM machines.
What makes the rotary knob special
The rotary knob replaces the valve wheel on your ECM and gives the machine a personal, warm touch. Olive wood shows a lively, high-contrast grain. At its core is a 7mm internal square profile made of stainless steel that fits onto the valve spindle. Since wood is a natural material, each grain is unique.
We partner with ECM, and a wooden rotary knob gives the machine your personal touch. Our opinion is one of many.
