Allied Moulded 9304 – Frequently Asked Questions

1) Will the Allied Moulded 9304 ceiling box hold a light fixture, and what size is it?
The 9304 is a fixture support box, molded specifically to give a ceiling-mounted lighting fixture a mounting point. It measures 3-3/8 x 5/8 inches with 3.5 cubic inches of interior volume, so it is a shallow pancake-style box for the fixture itself plus the splices, not a device box for stacking multiple cables.
2) Can I use the Allied Moulded 9304 to hang a ceiling fan?
No. The 9304 is described as a ceiling fixture support box for light fixtures and similar ceiling devices, with only 3.5 cubic inches of volume and a 5/8 inch depth. A paddle fan needs a box specifically marked and listed for fan support with a rated brace or bar hanger. Use the 9304 for lighting and buy a listed fan-rated box or fan brace kit for the fan location.
3) How many wires fit in a 3.5 cubic inch ceiling box?
Volume is the limit here, not the number of ports. The 9304 gives 3.5 cubic inches of usable interior space, which is tight. Standard box fill math counts 2.0 cubic inches per 14 AWG conductor and 2.25 per 12 AWG, with the fixture wires and any clamps counted too, so a 3.5 cubic inch box is meant for one small splice at the fixture, not a junction point where circuits pass through. If you are feeding through, step up to a deeper box.
4) Is the Allied Moulded 9304 non-metallic, and do I still need to run a ground?
It is non-metallic, molded from fiberglass reinforced polyester BMC, so the box itself is non-conductive and there is nothing to bond the way you would bond a steel box. The equipment grounding conductor in the cable still has to be carried through and connected to the fixture. What the fiberglass buys you is no rust and no corrosion in damp or chemically aggressive spaces where a steel box fails.
5) Why choose a fiberglass ceiling box over PVC or steel for a damp location?
Fiberglass reinforced polyester BMC sits between the two: it will not rust or corrode like steel, and it is a stiffer, more impact-resistant molded material than thermoplastic PVC. The 9304 is aimed at installs where a metallic box would corrode, such as unheated or humid ceilings, while still giving a rigid fixture support point. For dry, ordinary residential ceilings a steel or PVC pancake box does the same job; the fiberglass is what you reach for when the environment is the problem.
6) What is the exact part number for the Allied Moulded fiberglass pancake ceiling box?
Order it as Allied Moulded 9304, part of the FiberglassBox line of non-metallic enclosures. That number covers the 3-3/8 x 5/8 inch, 3.5 cubic inch ceiling fixture support box in fiberglass reinforced polyester.
7) Is the Allied Moulded 9304 suitable for a commercial building or only houses?
Both, within limits. It is intended for residential and light commercial electrical work, new construction and remodel wiring alike. For a property manager standardizing fixture boxes across units, the 9304 gives one non-corroding part number for shallow ceiling fixture locations; for heavier commercial fixture loads or larger conductor counts, the 3.5 cubic inch volume will be the constraint.
