Metallics RB54 – Frequently Asked Questions
1) What size conduit does the Metallics RB54 reducing bushing adapt?
The RB54 is a steel reducing bushing that takes a 2 inch opening down to 1-1/2 inch conduit, so you can run 1-1/2 inch rigid steel conduit into a fitting, box or enclosure hub sized for 2 inch.
2) I have a 2 inch knockout but I'm only running 1-1/2 inch conduit -- is the RB54 what I need?
That is exactly the job it does. The RB54 fills the oversized 2 inch opening and gives you a threaded 1-1/2 inch landing for the conduit, instead of leaving a gap at the box. Order one per oversized opening.
3) Is the Metallics RB54 reducing bushing steel or plastic?
Steel. That matters on rigid and IMC steel conduit runs where the fitting is part of the equipment grounding path and where a nonmetallic bushing would not be accepted.
4) How do I order the Metallics RB54 -- are there different versions?
One configuration only. The RB54 is ordered by that model number and covers the 2 inch to 1-1/2 inch reduction; there are no finish or material options to specify. For other size steps you would order the matching reducing bushing part number for that pair of trade sizes.
