Anti-Electrolysis Rail Bolt Zinc Anode voltage_360-460V Three Phase This ceramic pool depth markerThe Anti Electrolysis Rail Bolt Zinc Anode eliminates plaster staining and metal corrosion due to galvanic corrosion. Permanently bolts to ladder or grab rail below water line. A must for salt water pools. The Zinc Anode will sacrifice itself and corrode before all other metals in the pool. In doing so, the anode protects other metal parts from galvanic corrosion.
