Allied Moulded 9351-NKFR – Frequently Asked Questions

1) Is the Allied Moulded 9351-NKFR rated to hold a ceiling fan, or just a light fixture?
The 9351-NKFR is built as a ceiling fan and fixture support box, so it is intended to carry the structural load of a ceiling-mounted fan as well as a light fixture. That is the distinction from a plain round ceiling box, which is only meant to hold wiring and a lightweight luminaire. If you are hanging a fan, this is the box type you want.
2) What size is the Allied Moulded 9351-NKFR box and how much wiring volume does it give me?
It measures 4 inches by 2-7/16 inches with 22.5 cubic inches of interior volume. That volume is what governs your conductor fill count, so tally your wires, devices and clamps against 22.5 cubic inches before you box in a fan with a remote receiver or extra travelers.
3) Will a fiberglass box like the 9351-NKFR hold up in a damp or corrosive ceiling, like a garage or a coastal building?
Fiberglass reinforced polyester BMC is non-metallic, so it will not rust or corrode the way a steel box does in humid or salt-air ceilings. That is the main reason contractors pick it over a metal pan box in parking structures, laundry rooms, and coastal multi-family work. It is not a substitute for a listed wet-location enclosure, though; this is a support box for ceiling fans and fixtures.
4) How is the 9351-NKFR different from a standard plastic PVC ceiling box?
Material and purpose. A common PVC or thermoplastic ceiling box is molded plastic intended for wiring and light fixtures; the 9351-NKFR is fiberglass reinforced polyester BMC from Allied Moulded's FiberglassBox line and is purpose-built as a fan/fixture support box. If your ceiling opening is getting a fan, the PVC box is the wrong part.
5) Can I use the 9351-NKFR in a remodel where I am cutting into an existing ceiling?
Yes, it is used in both renovation and new construction ceiling work. At 4 by 2-7/16 inches it drops into a standard ceiling opening, and the 22.5 cubic inch interior leaves room for the splices you make when you re-feed an existing fixture location. What it does not include is a brace or bar hanger, so the box still needs solid framing or a support bar to attach to.
6) What is the exact part number to order this Allied Moulded fan box, and is there more than one version?
Order it as Allied Moulded 9351-NKFR. It is a single configuration, not a family of sizes or colors, so the model number is all you need to specify.
7) Is the Allied Moulded 9351-NKFR suitable for commercial jobs or is it residential only?
Both. It is specified for residential electrical installations and light commercial ceiling installations, which covers apartment and multi-family fan replacements, hospitality guest rooms, and similar fixture support work.
