RACO 1292 Threaded Iron Coupling

The RACO 1292 is a zinc-plated iron grounding bushing designed for 3-inch threaded metallic conduit. It suits electricians and installers joining rigid metal conduit or intermediate metal conduit in commercial and industrial wiring systems.

CSA Certified UL Listed 3-Inch NPS Thread

This fitting carries CSA certification and UL listing for code-compliant installations. The female NPS thread accepts 3-inch trade-size RMC or IMC, while the insulated throat protects conductors during pulling.

Questions about this item

What does the 3 in trade size mean when I install this bushing?

It matches 3 in threaded metallic conduit such as RMC or IMC, giving a secure threaded connection for that conduit size.

How does the NPS thread standard limit what I can connect?

The female NPS threads accept male NPS-threaded conduit or fittings of the same 3 in size, so only matching NPS components will seal properly.

What clearance do I need for the bushing's overall height and width?

The bushing measures 4 15/32 in in both overall height and width, so allow at least that much space in the enclosure or junction box.
