Smooth, threaded, self-extending copper-plated steel earthing rods provide effective grounding for lightning protection. Easy to assemble, they adapt to various soil depths. Copper coupling sleeves ensure robust connections between rods. Driving heads and caps protect the rods during installation. Brass connecting lugs ensure a reliable connection between the rods and down conductors. Inspection chambers, made of plastic or cast iron, offer easy access to underground connections, thus completing the lightning protection grounding system.
