PROVIDES FULL ELECTRICAL
SYSTEM PROTECTION
Allied RIGID is precision manufactured for
dependable, long-lasting value and
protection for the electrical raceway system.
Manufactured from high-strength steel, Allied
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 RIGID is hot-dipped galvanized inside
and out. It is top-coated with a compatible
organic layer to inhibit white rust and
increase corrosion resistance.
Allied RIGID 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 and sharp and also provide
instant trade size recognition. Even trade
sizes are color-coded blue, 1/2 trade sizes
are black, and 1/4 trade sizes are red.
EMI SHIELDING
Allied RIGID greatly reduces electromagnetic
fields, effectively shielding computers and
sensitive electronic equipment from the
electromagnetic interference caused by power
distribution systems. For further information,

GEMI (Grounding and ElectroMagnetic
Interference) analysis software and related
research papers.
FULL CODES AND STANDARDS
COMPLIANCE
Allied RIGID is covered by article 344 of the
National Electrical Code. It is listed to
Underwriters Laboratories Safety Standard
U.L. 6. and is manufactured to ANSI C80.1,
both of which have been adopted as Federal
Specifications in lieu of WWC 581.
Allied RIGID is recognized as an equipment
grounding conductor by NEC Article 250.
Documentation for compliance with NEC
Article 250 is also available in the GEMI
(Grounding and ElectroMagnetic Interference)
analysis software and related research studies
found at the www.alliedeg.com website.
Installation of Rigid Metal Conduit shall
be in accordance with the National Electrical
Code and U.L. General Information card #DYIX.
Master bundles conform to NEMA standard RN2.
