Allied Moulded 9351-NK Fiberglass Ceiling Fixture Support Box, 4-Inch x 2-7/16-Inch

The Allied Moulded 9351-NK is a FiberglassBox™ ceiling fixture support box engineered from fiberglass reinforced polyester BMC (bulk molding compound), a rugged non-metallic material built for long-term durability in demanding installation environments. Sized at 4-Inch x 2-7/16-Inch with a 22.5-Cubic-Inch interior capacity, this support box is purpose-built to securely mount and support ceiling-mounted lighting fixtures and similar devices. As a non-metallic enclosure, it resists corrosion, moisture intrusion, and the deterioration that can affect traditional steel boxes over time, making it a dependable choice for electricians who need a lightweight yet strong support solution. The fiberglass reinforced polyester BMC construction delivers excellent dimensional stability and impact resistance while remaining easy to handle and install on the jobsite.

  • Ceiling Fixture Support Design: Purpose-built as a support box for ceiling-mounted fixtures, providing a secure mounting point for lighting and similar devices.
  • FiberglassBox™ Series: Part of Allied Moulded's FiberglassBox™ product line, known for combining lightweight handling with rugged, non-metallic performance.

Allied Moulded 9351-NK – Frequently Asked Questions

1) What size is the Allied Moulded 9351-NK ceiling box and how much wire volume does it give me?
The 9351-NK measures 4 inches by 2-7/16 inches with a 22.5 cubic inch interior. That volume is what decides your conductor fill count under box fill rules, and it also has to cover the fixture support hardware sitting inside the box, so count that space before you pack the splices in.
2) Can I hang a light fixture directly from the Allied Moulded 9351-NK?
Yes, that is what it is built for. The 9351-NK is a ceiling fixture support box, so it provides the mounting point for ceiling-mounted lighting and similar devices rather than acting as a plain junction box.
3) Is the 9351-NK plastic or fiberglass? Will it hold up better than a PVC box?
It is molded from fiberglass reinforced polyester BMC (bulk molding compound), not standard thermoplastic. BMC gives you better dimensional stability and impact resistance than a common plastic box, which matters on an overhead support box that carries a fixture load.
4) Will a fiberglass ceiling box corrode in a damp interior space like a laundry room or a parking garage soffit?
No. The 9351-NK is non-metallic, so it will not rust or corrode the way a steel box can in damp or corrosive interior conditions. Allied Moulded lists it for interior installations where corrosion resistance is a priority.
5) What part number do I order for the Allied Moulded FiberglassBox ceiling support box?
Order model 9351-NK. It is the Allied Moulded FiberglassBox line ceiling fixture support box in the 4 inch by 2-7/16 inch, 22.5 cubic inch size, and it ships as a single model with no finish or size options to specify.
6) Is the 9351-NK meant for new construction rough-in or for cutting into an existing ceiling?
Allied Moulded lists the 9351-NK for both new construction and remodel electrical work, covering residential and commercial rough-in. If you are standardizing boxes across a building, it is the same part either way, which keeps the stock room simple.
7) Is a fiberglass ceiling box easier to handle overhead than a metal one?
Yes. The BMC composite build keeps the 9351-NK lighter than a comparable metal box, which is a real difference when you are working off a ladder setting boxes in a ceiling all day.
