Features & Benefits:
- The mil-spec alloy includes about 5% Zinc and a trace of Indium to prevent oxidation resulting in a layer reducing the sacrificial properties of the anode.
- Provides more protection and will last longer than zinc anodes of the same size (up to 50% longer).
- Less than half the weight of of a similar sized zinc anode.
- Provides superior support compared to zinc anodes in fresh or brackish water, while still giving excellent protection in salt water, and is the only anode that is safe for all applications.
