The Allied Bolt Copper Staple (vendor part 25008, Millennium part 528143) measures 1-1/2 in x 3/8 in x 0.162 in and secures copper ground wire to wood utility poles, packed 50 per pack. The electrically deposited copper coating on AISI 1008 steel limits galvanic corrosion where the staple contacts bare copper grounding wire outdoors. Its larger size handles heavier gauge ground wire than Millennium's 1-1/4 in copper staple option. Order alongside ground rods and tap clamps to complete a pole grounding and bonding installation.
