These anodes are made with an aluminum alloy which is specially formulated for marine anode use.
They last longer than zinc anodes and, utilizing a less toxic activator, are safer for the environment.
Very easy to install, these zinc anodes have slotted mounting holes so they fit most applications without the need for custom drilling.
They are built around a high-strength slotted steel mounting insert.
Unlike some competing brands, the steel insert in Sea Shield anodes is galvanized for longer shelf-life and better grounding.
