Quality Long Lasting GRC (Rigid) Allied Tube & Conduit Rigid Steel Conduit is precision manufactured for dependable, longlasting value and ultimate protection for electrical conductors. Highly resistant to damage from impact, it can be installed in all occupancies and in all locations, including Class I Division 1 hazardous locations. Rigid steel conduit, covered by Article 344 in the National Electric Code® (NEC), is recognized as an equipment grounding conductor in Article 250-118 of the NEC and also provides excellent shielding from electromagnetic fields.
WEIGHTS & DIMENSIONS
SPECIFICATIONS FULL ELECTRICAL SYSTEM PROTECTION Manufactured from high-strength steel, Allied Tube & Conduit RIGID combines damage-resistant strength with ductility to assure easy bending, cutting and joining. It also provides smooth, continuous raceways for fast wire-pulling. No need to worry about damage to the conduit system even when pulling through multiple 90° bends. Allied Tube & Conduit RIGID is hot-dipped galvanized inside and out. It’s top-coated with a compatible organic layer to protect against white rust and increase corrosion resistance. It is impact and crush resistant for maximum conductor protection. The 3/4″ taper NPT threads (ANSI B1.20.1) are full cut and hot galvanized after cutting. Color-coded end-cap thread protectors keep the threads clean, sharp and also provide instant trade size recognition. Trade sizes are color-coded blue, 1/2 trade sizes black, and 1/4 trade sizes red. EMI SHIELDING Allied Tube & Conduit RIGID is very effective in reducing electromagnetic field levels for encased power distribution circuits, shielding computers and other sensitive electronic equipment from the effects of electromagnetic interference.

FULL CODES & STANDARDS COMPLIANCE Allied Tube & Conduit RIGID is covered by article 344 of the National Electrical Code. It is listed to Underwriters Laboratories Safety Standard UL 6. and is manufactured to ANSI C80.1, both of which have been adopted as Federal Specifications in lieu of WWC 581. Allied Tube & Conduit RIGID is recognized as an equipment grounding conductor by NEC Article 250. Installation of Rigid Metal Conduit shall be in accordance with the National Electrical Code and UL General Information card #DYIX. Master bundles conform to NEMA standard RN2. SPECIFICATION DATA RIGID Metal Conduit shall be hot-dip galvanized steel equal to that manufactured by Allied Tube & Conduit Corporation. Threads shall be hot galvanized after cutting. RIGID shall be produced in accordance with UL Safety Standard #6 and ANSI C80.1 and shall be listed by a nationally recognized testing laboratory with follow-up service. Where Kwik-Couple® Rigid is used it shall also meet UL Safety Standard 514-B. It is noted that these UL standards have been adopted by the federal government and separate military specifications no longer exist.
