Features & Specifications
Allied’s patented Super Kwik-Couple® IMC reduces threaded conduit installation time and cost significantly. Super Kwik-Couple® has an integrated coupling on the conduit exactly where you need it. Allied Super Kwik-Couple® Intermediate Metal Conduit (IMC) is precision manufactured for economical protection and long lasting value for the electrical raceway system. Manufactured from premium, work hardened steel combining electrical and mechanical performance with ductility. Super Kwik-Couple® IMC is resistant to impact and is easy to cut, bend and join for smooth, continuous raceways. Allied’s Super Kwik-Couple® IMC is as strong, lighter in weight, and less expensive than Rigid. In fact, it can save you as much as 30% in overall costs. Intermediate Metal Conduit, covered by Article 342 in the National Electrical Code (NEC), is recognized as an equipment grounding conductor in Article 250 of the NEC and also provides excellent shielding from electromagnetic fields.

The Allied Advantage
Allied’s Super Kwik-Couple® IMC has a larger internal diameter than RIGID conduit allowing for easier fishing and wire-pulling. Super Kwik-Couple® IMC is also more “rigid” than RIGID to provide exceptional wiring protection in many applications.

Allied IMC uses the same threaded couplings and fittings as RIGID conduit, and the 3/4” NPT threads (ANSI B1.20.1) are also full cut and galvanized after cutting. Color-coded end-cap thread protectors keep the threads clean and sharp, and also help to provide instant trade size recognition. Even sizes are color-coded orange, 1/2 trade sizes are yellow, and 1/4 trade sizes are green.

Allied’s IMC is hot galvanized using Allied’s patented inline Flo-Coat® process. This process combines zinc, a conversion coating, and a clear organic polymer topcoat to form a triple layer of protection against corrosion and abrasion. The interior of Allied IMC is coated with a highly corrosion-resistant lubricating finish for easier wire-pulling. No need to worry about damage to the conduit system even when pulling through multiple 90° bends.

EMI Shielding
Super Kwik-Couple® IMC is very effective in reducing the effects of electromagnetic fields on encased power distribution circuits, shielding computers and other sensitive electronic equipment from the effects of electromagnetic interference.
