Rigid Metal Conduit (RMC)

Our Rigid Metal Conduit (RMC) is precision manufactured for reliable, long-lasting value and complete protection for your electrical raceway systems. Manufacturing with high-strength steel allows our RMC to be damage resistant while also allowing bending flexibility to meet your installation needs. Our rigid metal conduit is hot-dipped galvanized with a smooth interior and exterior allowing for easy pulling of wires during installation. It is also coated with a chromate to protect against white rust.
Our threads, 3/4” taper NPT threads (ANSI B1.20.1) are galvanized after cutting to ensure that the threads will be protected against corrosion.
