Allied Moulded 9351-NKFRV – Frequently Asked Questions

1) Is the Allied Moulded 9351-NKFRV rated to hang a ceiling fan, or is it fixture-only?
The 9351-NKFRV is a ceiling fan/fixture support box, so it is built to carry an overhead ceiling fan as well as a light fixture. That is the distinction that matters on a rough-in: a plain ceiling box is for luminaires only, while a fan support box gives you the secure mounting point a fan needs. Use it where you are hanging fans, hanging fixtures, or want one box that covers either at the same location.
2) What size opening does the Allied Moulded 9351-NKFRV need in the ceiling?
The box measures 4 x 2-7/16 inches, a compact round-style footprint sized for standard ceiling fan and fixture support applications. Lay that out against your joist bay and drywall cut before rough-in. The 2-7/16 inch figure is the depth-class dimension, so verify you have clearance above the ceiling plane where insulation, ductwork or a second-floor subfloor is tight.
3) Why use a fiberglass ceiling box instead of a steel one?
The 9351-NKFRV is molded from fiberglass reinforced polyester BMC, so it will not rust or corrode the way a steel ceiling box does in damp or humid locations. BMC also resists impact and holds its structural integrity over time. For property managers and MRO buyers dealing with bathrooms, laundry rooms, covered exteriors or coastal buildings, that corrosion resistance is the main reason to specify non-metallic here. Steel is still the habit on dry interior work, but it degrades where moisture is present.
4) Do I still need a grounding conductor with a non-metallic ceiling box?
Yes. BMC is non-conductive, so the 9351-NKFRV cannot serve as an equipment grounding path the way a metal box bonded to metal raceway can. Carry your equipment grounding conductor through to the fan or fixture and splice it inside the box. This is standard practice with any non-metallic enclosure and is worth flagging to anyone swapping from steel boxes on a retrofit.
5) What is the exact manufacturer part number for this Allied Moulded fan box?
Allied Moulded part number 9351-NKFRV, from the FiberglassBox line. Order and cross-reference against that number rather than a generic description, since Allied Moulded's ceiling box family runs several suffix variations that differ in bracket and mounting configuration.
6) Can the 9351-NKFRV be used on commercial jobs or is it residential only?
Both. Allied Moulded lists it for residential electrical rough-in and light commercial ceiling installations, which covers apartment and multi-family work, hospitality guest rooms and general office ceiling fixtures. It is not positioned for heavy industrial enclosure duty.
