Plain, 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 guarantee robust connections between rods. The striking heads and dowels protect the rods during installation. Brass connector lugs ensure a reliable connection between rods and tape conductors. Inspection manholes, made of plastic or cast iron, provide easy access to underground connections, thus completing the lightning rod earthing system.
