Grounding metallic conduit bushing with insulated throat is a comprehensive safety solution for conduit terminations. It combines three critical functions: an integrated grounding lug for a secure grounding conductor connection, a built-in nylon lining that protects wires from abrasion and prevents electrical faults, and a smooth, rounded edge that safeguards wire insulation from the conduit’s sharp cut end.
