Magnesium Drive-In Anodes
Magnesium drive-in anodes are an extruded magnesium rod which has a machined “spike” or “cut” end which allows the anode to be directly driven in to the ground with no requirement for pre-digging.
Drive in anodes are assembled with a hexagonal head and threaded mounting cap. As standard 3FT of #12AWG TW wire is connected.
SS clamps are available for anode to structure connection.
