Full Electrical System Protection

Manufactured from mild steel, Allied’s Rigid Conduit is highly

resistant to damage from impact yet ductile to facilitate bending.

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. Even sizes are color-coded blue, 1/2 sizes black, and

1/4 sizes red.

Coatings

Hot-dip galvanized inside and out to provide galvanic corrosion

protection. Also topcoated with a compatible organic layer to

protect against white rust. The inside surface is evenly coated for

wire-pulling ease, even through multiple 90° bends.

EMI Shielding

Allied Rigid Steel Conduit is very effective in reducing the effects

of electromagnetic ﬁeld levels for encased power distribution

circuits, shielding computers and other sensitive electronic

equipment from the effects of electromagnetic interference.
