Steel City HO 224 1 1/4 NIPPLE, OFFSET 3/4,RGD/IMC,

It's a 1-1/4 inch offset nipple with a 3/4 inch offset, used to join two runs of rigid or IMC conduit that don't line up on the same centerline, most often where a box or enclosure knockout sits off-axis from the raceway. Instead of bending conduit or adding fittings to make up the difference, the nipple carries the 3/4 inch step built in. It's sold each.

Yes, it's built for both RGD and IMC in the 1-1/4 inch trade size. Rigid and intermediate metal conduit share the same NPT taper thread at a given trade size, so one nipple covers both. It will not work on EMT, which is unthreaded and uses set-screw or compression couplings.

The two threaded ends sit on parallel centerlines 3/4 inch apart. So if your knockout is 3/4 inch out of line with the conduit run, this nipple takes up that shift in one piece. If your misalignment is larger or smaller than 3/4 inch, you want a different offset nipple or a field bend, not this one.

Zinc die cast. That's a cast fitting, not a machined steel nipple, so treat it as a fitting body rather than something to wrench on hard with a pipe wrench. It's intended for the same dry and general indoor raceway work as other die cast conduit fittings.

It's an offset nipple, catalogued alongside couplings because it joins two conduit ends. Both ends are threaded male, so you make up to female hubs, enclosure hubs, or locknut-and-bushing at a knockout. If you're landing it in a sheet metal knockout rather than a threaded hub, you'll need locknuts and a bushing, which are separate items.

Order it as Steel City HO 224. It's manufactured in India, which is the country of origin line a government or institutional buyer will need for procurement paperwork.
