The Allied Bolt Copper-Coated Staple (vendor part 25001, Millennium part 527679) is a 1-1/4 in x 1/4 in staple for securing ground wire to wood utility poles where electrical continuity and corrosion resistance matter. AISI 1008 steel with an electrically deposited copper coating pairs metallurgically with copper ground wire to reduce galvanic corrosion at the fastening point. It's the preferred staple for bonding and grounding runs versus standard galvanized staples used for molding. Millennium stocks matching copper ground rods and bonding clamps to complete the grounding system.
