IMC is manufactured as a cross between EMT and rigid metal conduit (RMC). A slightly thinner gauge than RMC, IMC is light but strong. It has the same electric-resistance welded tube-making process as EMT, but it is threaded like RMC, so the same couplings can be used for both. Like all of our electrical conduit, it is protected by zinc and organic coatings inside and out, and is thoroughly tested for bendability and threadability before being shipped.
Trade sizes: ½–4
Lengths: 10′
Compliance: UL-1242, ANSI® C80.6, NEC® Article 342, WW-C-581
Because IMC is made of less steel, it has a larger inside diameter — allowing for easier wire pulling.
SpeedCouple, our pre-installed swivel coupling, connects IMC in half the time and cuts material costs by as much as 50%, compared with three-piece couplings. It’s just one of our three Conduit Kits.
