Steel City RB 121 – Frequently Asked Questions

1) What size conduit does the Steel City RB 121 reducing bushing adapt?
The RB 121 takes a 3/4 inch hub or fitting opening down to 1/2 inch conduit. It's a reducing bushing for rigid and IMC conduit, so the male thread goes into the 3/4 inch tapped opening and the 1/2 inch female thread accepts your smaller conduit.
2) Can I use a reducing bushing to land 1/2 inch conduit in a 3/4 inch box knockout or enclosure hub?
That is exactly what the RB 121 is for. Where an enclosure, box hub, or fitting is tapped for 3/4 inch and the run is 1/2 inch rigid or IMC, the bushing threads into the larger opening and gives you a 1/2 inch female thread. It saves changing the enclosure or drilling a new opening.
3) Is the Steel City RB 121 bushing steel or plastic?
Steel. It is a threaded steel reducing bushing, which is why it's specified for rigid metal conduit and IMC rather than for nonmetallic raceway. Steel body also keeps the raceway path metallic through the reduction.
4) What part number do I order for a 3/4 to 1/2 inch Steel City reducing bushing?
Order Steel City RB 121. That is the manufacturer part number for the 3/4 inch to 1/2 inch steel reducing bushing for rigid and IMC conduit.
5) Does a reducing bushing protect the conductors the way an insulated bushing does?
No, it's a size adapter, not a wire-protection bushing. The RB 121 reduces a 3/4 inch threaded opening to 1/2 inch; if you need a smooth or insulated throat where conductors leave the raceway, add a separate insulated or insulating metallic bushing on the 1/2 inch thread.
