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.
