Notice: Our knobs do not include a free shaft to support the Zero Waste movement. If you need to drill fitment, please buy this shaft yourself. Gomexus power knobs are constructed from aero aluminum and are color anodized for saltwater corrosion resistance. The unique design makes them easy to rinse and maintain. Stainless steel hardware with aluminum bushings are included.
