Corrosion-Inhibiting Rods and Pads
Also known as sacrificial anodes, these rods and pads protect tanks, water heaters, and heat exchangers from rusting by attracting corrosion that would otherwise damage equipment.
Zinc alloy pads provide corrosion protection in salt water.
Aluminum alloy pads last longer than zinc alloy and can be used in fresh water as well as salt water.
Rectangular pads have a mounting wire.
Circular and square pads have a mounting hole.
