These Wallis high-strength threaded couplings (also referred to as Earth Rod Couplings & Earth Rod Couplers) are used for joining copperbond earth rods together. They facilitate deep driving and ensure continual contact between the earth rods both during and after installation.
These couplers also protect the earth rods threads during installation with the threaded driving head. There is also a lead-in for ease of assembly and the unique hexagonal design allows for greater grip and keeping the coupling tight when driving into the ground.
All Wallis threaded couplings are manufactured from a high copper content alloy ensuring excellent corrosion resistance.
Used in conjunction with Copperbond Earth Rods.
