Bridgeport Fittings 388-DC40 3" Insulated Grounding Bushing, Zinc Die-Cast with Lug

The Bridgeport Fittings 388-DC40 is a 3" insulated grounding bushing built from rugged zinc die-cast material and equipped with an integral grounding lug. It is engineered to terminate rigid and intermediate metal conduit (IMC) runs while protecting conductor insulation from abrasion at the point where wiring exits the raceway. The insulated throat shields conductors from sharp conduit edges, and the zinc die-cast lug provides a dependable termination point for the equipment grounding conductor, helping electricians maintain continuous, reliable bonding throughout the raceway system. This 3" size fits standard rigid and IMC conduit terminations commonly specified on commercial and industrial electrical projects where dependable grounding continuity is essential to a safe, functioning system.
