Allied Moulded 9350-HLK – Frequently Asked Questions

1) Can the Allied Moulded 9350-HLK box be used to hang a ceiling fan?
The 9350-HLK is built as a ceiling fixture support box, intended to carry light fixtures, fans, and similar ceiling-mounted devices. Follow the fan manufacturer's weight requirements for the specific unit you are hanging, and mount the box to framing during rough-in as the new work design intends.
2) Is the 9350-HLK a new work or old work (remodel) box?
New work only. It is configured to be fastened directly to framing before the finished ceiling goes up, so it is a rough-in item. For cutting into an existing finished ceiling you need an old work / retrofit fixture support box instead; the 9350-HLK has no provision for clamping to drywall.
3) How many conductors will a 22.5 cubic inch ceiling box hold?
The 9350-HLK gives you 22.5 cubic inches of interior volume. Under NEC box fill rules that translates to about eleven 14 AWG conductors or ten 12 AWG conductors at 2.00 and 2.25 cubic inches each, before you subtract volume for the fixture stud, clamps, and devices. For a simple feed-through with a fixture whip, that is generous room.
4) What size opening does the Allied Moulded 9350-HLK take up in the ceiling?
Trade size is 4-Inch x 2-7/16-Inch, so it is a standard round-profile ceiling box footprint that most ceiling fixture canopies and fan canopies are sized to cover.
5) Why use a fiberglass ceiling box instead of a metal one?
The 9350-HLK is molded from fiberglass reinforced polyester BMC. It is non-conductive, so there is no need to bond the box itself, and it resists the corrosion, cracking, and moisture damage that shortens the life of metallic boxes. That makes it a reasonable pick for damp-prone ceilings such as garages, porch soffits, and laundry areas, and for light commercial work where corrosion is a concern.
6) Is the 9350-HLK suitable for commercial ceiling work or residential only?
Both, within limits. Allied Moulded lists it for residential ceiling installations and light commercial ceiling electrical work. For heavy industrial or wet-location assemblies you would step up to an enclosure rated for that environment.
7) What is the exact part number to order this Allied Moulded ceiling fixture box?
Order it as Allied Moulded 9350-HLK. That is the manufacturer part number, part of the FiberglassBox line.
