This ground wire clamp is designed for stable and reliable grounding in demanding industrial environments. It uses a three-point copper pin structure that provides multiple contact points to minimize contact resistance and improve conductivity. The clamp body is made of corrosion-resistant aluminum alloy, paired with a PU-coated tinned copper core to ensure long-lasting performance even in harsh conditions. The coiled cable measures 1.5 ft and stretches up to 16.4 ft, offering excellent reach while preventing tangling. A high-strength retractable spring helps the clamp maintain firm grip and resist deformation during repeated use. Ideal for fuel stations, tank farms, refineries, chemical plants, substations, and other locations where grounding is required during filling, loading, or transfer operations.
