Galvan Industries 6254-10M is a 5/8 in by 4 ft copper clad steel ground rod with 10 mil cladding. The steel core takes driving force without bending while the bonded copper layer provides the conductivity and corrosion resistance a grounding electrode needs over decades in soil. The 4 ft length suits shallow-bedrock sites, pedestal and cabinet grounds, and locations where multiple bonded rods are used instead of a single deep electrode. A standard bonding and grounding item for telecom and utility construction. Millennium part #526319.
