Description
MATERIAL: Clamp body is ductile iron, grade 654512. The bolt and nut are steel. The washers are brass and/or stainless steel.
FINISH: Body is hot-dip galvanized per ASTM A-153. The bolt and nut are galvanized. The brass retaining washer is tin-plated.
APPLICATION: For use with galvanized ground rods. The RC – 58GW and RC – 34GW are recommended for use with copper ground wire. They feature tin-plated brass and/or stainless steel retaining washers which effectively separates the copper ground wire from the galvanized clamp body. This design minimizes bi-metallic galvanic corrosion and increases clamp performance.
