When installing multiple sacrificial anodes inside a tank, it is extremely important to consider supporting the anodes. Using a Wooden Anode Support Roller by Bell, not will you support the anode from sagging over time, but you also can easily roll the anode into position from the access port.

The support roller is to be installed inside the tank at the end of the anode support arm. The support roller isolates the anode from the support arm, not allowing the anode and structure metals direct contact. The roller and support arm will bear the weight of the anodes so the anodes do not sag over time.
