Very easy to install, these zinc anodes have slotted mounting holes so they fit most applications without the need for custom drilling.
Both these anodes have the same dimensions, but the slots are different widths to accomodate a variety of installations.
These anodes 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.

ZHC-10 can replace most transom-mounted zincs, including Bayliner factory zincs
