A window crank is used to manually operate a window within your vehicle. It is also referred to as a window handle or winder. Through use, this crank could become loose and eventually break off, which will then need replacing. Febi Bilstein's range includes more than 20,000 spare parts for all popular types of cars and commercial vehicles. This window winder is black and is designed to be used as originally intended, not modified for purpose. Please ensure the product is installed by a competent individual. The product is usually supplied without fitting instructions.
