70MM BUTTON ANODE

The 70mm Zinc Anode is ideal for smaller craft and its most common purpose is for mounting on the rudder to give complete protection. The Zinc anodes you use on a vessel are called “Sacrificial Anodes.” Zinc is used because it has a higher voltage in the water so the current will be more inclined to flow from it than from your propeller. To complete the electrical circuit, the zincs must be connected to the items they are intended to protect.
We carry a wide range of Zinc anodes in Stock for saltwater use. Hole Size suitable for up to M12 Bolt.

BACKING PADS OR FIXINGS ARE NOT INCLUDED.
