Anode Rod Sizes
Rod Diameters
Anode rods are extruded in twelve standard diameters ranging from 0.500” to 2.562”, as pictured with plain ends. Each rod has a steel core wire running lengthwise through its center. These anode rods can be cut to any length and configured for various cathodic protection applications. See chart below for anode rod sizes, specifications, and tolerances.
