This kidney shaped anode works as a sacrificial metal structure to protect the helmet from corrosion, especially in saltwater conditions.
NOTICE:
Replace anodes when deterioration interferes with proper fitting or anodes become loose
fitting. Do not paint or coat zinc, negating the anode’s functionality. Ensure good metal-to-metal contact when installing the kit and for the duration of the anode kit implementation;
failure to do so will render the kit ineffective.
