Allied Moulded 9351-NKV Fiberglass Ceiling Fixture Support Box

The Allied Moulded 9351-NKV is a FiberglassBox™ ceiling fixture support box engineered from fiberglass reinforced polyester BMC (bulk molding compound), built to support lighting fixtures and ceiling-mounted electrical devices in a compact, durable enclosure. Measuring 4-Inch x 2-7/16-Inch with a 22.5-cubic-inch interior capacity, this box is sized for standard ceiling fixture applications where a non-metallic, corrosion-resistant enclosure is preferred over traditional steel boxes. Fiberglass reinforced polyester construction provides strength and dimensional stability while remaining lightweight and resistant to moisture, corrosion, and chemical exposure, making it a reliable choice for both new construction and retrofit ceiling fixture installations.

Allied Moulded 9351-NKV – Frequently Asked Questions

1) What size opening does the Allied Moulded 9351-NKV ceiling box fit, and how much wiring room does it give me?
The 9351-NKV is a 4 inch by 2-7/16 inch round ceiling fixture support box with 22.5 cubic inches of interior volume. That footprint drops into a standard 4 inch ceiling fixture opening, and the 22.5 cubic inch capacity is what you work against when you count conductors, clamps, and fixture leads for box fill.
2) Can I hang a light fixture directly off this box, or do I need a separate fixture bar?
This is a fixture support box, not a plain junction box, so it is built to carry a ceiling-mounted lighting fixture rather than just house splices. Allied Moulded's fiberglass reinforced polyester BMC body gives it the structural strength for that duty. It is not a fan-rated box, so for a paddle fan use a box specifically listed for fan support.
3) Why choose a fiberglass box over a steel ceiling box for a damp or corrosive area?
Fiberglass reinforced polyester resists moisture, corrosion, and chemical exposure in a way a steel box does not, which is why the 9351-NKV gets specified in damp ceilings, wash-down areas, and coastal or chemical-exposed buildings. It is also non-metallic and lighter than steel, so there is less mass hanging off the ceiling framing. Steel is still the choice where you need the box itself as part of an equipment grounding path, since a non-metallic box requires you to carry the equipment grounding conductor through to the fixture.
4) Is the Allied Moulded 9351-NKV suitable for retrofitting an existing ceiling fixture box?
Yes, retrofit ceiling box replacement is one of its stated applications alongside new construction lighting. Because it is a 4 inch by 2-7/16 inch box, it swaps cleanly where a standard 4 inch round ceiling box is already cut in. Check the depth you have above the ceiling before ordering, since 2-7/16 inches needs that clearance between the joist or framing and the finished surface.
5) I'm standardizing ceiling boxes across a multi-family property. Does this one box handle both interior and damp ceiling locations?
For a property manager or MRO buyer trying to carry one part number, the 9351-NKV covers ordinary commercial and residential ceiling fixture wiring as well as corrosion-prone or damp ceiling environments, because the fiberglass reinforced polyester body does not rust the way a painted steel box does in a laundry room, garage ceiling, or pool enclosure. The limit is fixture weight class: it supports lighting fixtures, so anything requiring fan support gets a different box.
6) What is the exact part number I should order for this Allied Moulded fiberglass fixture box?
Order it as Allied Moulded 9351-NKV. That is the manufacturer part number and the only configuration, so there is no finish, size, or depth option to specify with it. It is part of the Allied Moulded FiberglassBox line.
