This coupling joins lengths of threaded copper bond earth rods together. They facilitate deep driving and ensure continual contact between the rods during and after driving.
The coupling also protects the rods threads while using the driving stud. The coupling has lead for ease of assembly and a hex on the outside for grip and keeping the coupling tight when driving into the ground.
Material: Gunmetal, Brass, Aluminium Bronze.
