Welcome to OEM and Let us know if you need further details or assistance!
Earth Rod Couplers are used for joining copper bond threaded earth rodstogether. They facilitate deep driving and ensure continual contact betweenthe rods both during and after installation. The coupling also protects theearth rod threads during installation with the driving head.
