[High Quality Ground Pin]- This ground rod is made of high quality material for lightning-protection. The bottom has a tapered design for quick release of current. The surface of the ground rod is electro-galvanized, which is more durable and not easy to rust. [STRONG AND EASY TO INSTALL]- Our ground rods are strong enough to hit the ground, not easy to bend, and come with pre-installed bolt wire clips to integrate with your wires. It is suitable for grounding construction under different soil moisture, temperature, pH value and resistivity changes. [Safe and Reliable]: Compared with the traditional construction method of pure copper grounding rod and grounding strip, the cost of copper-clad steel grounding electrode is greatly reduced. (And with a strength that pure copper ground rods can't achieve). Not only the hardness is strong, but also more suitable for lightning-protection, which is unmatched by copper rods [Wide Use]- Our ground rods are designed for grounding applications in antennas, satellite dishes, coaxial lines, electronic equipment, electronic fences, generators and other grounding applications. color:As shown Material:copper clad steel size:440mm Package Contents: 1 x grounding rod Only the above package content, other products are not included.
