Medium-Wall (IMC) and Thick-Wall (RMC) Metal Conduit and Fittings

The industry standards, IMC and RMC conduit systems offer the most durable protection indoors, outdoors, and underground. Both types have the same outside diameter, so they use many of the same fittings. This interchangeability makes retrofits easier and reduces the parts you need to keep on hand.

Conduit Bushings

Threaded

Connection

Threaded internally and externally to connect two different-sized pieces of conduit.

Zinc-Plated Steel—The strength of steel with a plating that protects from occasional exposure to moisture.

Aluminum—One-third the weight of steel that's the same size. Aluminum is also nonmagnetic to prevent electrical interference in nearby equipment.
