Thicker and sturdier than electrical metal tubing, rigid metal conduit (RMC) protects wires and cable in areas where external elements or impact are a concern. It is suitable for indoor, outdoor, wet, or dry conditions, can be buried underground, and can serve as an equipment grounding conductor.
Galvanized Rigid Steel Conduit (GRC)
Heavier and thicker than other rigid metal conduit, this conduit is made of corrosion-resistant galvanized steel. It can be used in both indoor and outdoor applications as well as underground.
Hot Galvanized Steel
Galvanized Rigid Steel Conduit (GRC) with Integrated Coupling
There's no need for a coupling or connector with this conduit. The integrated coupling is internally threaded so you can connect it with other threaded conduit and fittings.
Hot Dip Galvanized Steel
Aluminum Rigid Conduit (ARC)
Lightweight and corrosion resistant, this rigid metal conduit is made of aluminum. It is ideal for use in clean or harsh environments such as processing plants and paper mills.
