The Salisbury 2103 Screw Type Temporary Ground Rod is used when an adequate system ground is not available. The design incorporates a copperweld rod with bronze fittings screwed and pinned on both ends. The terminal on the handle is designed to accept cables equipped with a 5/8 -11 UNC threaded ferrule. As an alternative, a "C" clamp may also be attached directly to the ground rod shaft.
