Allied Moulded FiberglassBox Series Fiberglass Multi-Gang Switch Box

The Allied Moulded FiberglassBox™ series switch box is molded from fiberglass reinforced thermoset polyester and engineered for durable, long-term performance in residential and light commercial wiring installations. This family is available in 2-gang and 3-gang configurations (models 2302-NK and 3300-NK), giving installers a corrosion-resistant, dimensionally stable alternative to standard sheet-metal or plastic switch boxes for switch and receptacle rough-in work. Because each enclosure is molded from fiberglass reinforced polyester rather than stamped steel, it resists corrosion, cracking, and warping while holding its shape through rough-in, drywall, and finish work — a dependable choice wherever box integrity and accurate device placement matter.

Key Features

  • Multi-Gang Configurations: Available in 2-gang and 3-gang versions to accommodate multiple devices in a single residential/receptacle switch box installation.
  • Durable Construction: Molded from fiberglass reinforced thermoset polyester for a rigid, corrosion-resistant enclosure that resists cracking and warping compared to standard plastic boxes.
  • Consistent Wall-Cavity Fit: Each gang configuration is sized to fit standard wall cavity depths for new construction and remodel work.
  • Ample Interior Volume: Interior capacity scales with gang count, providing generous room for device and wire fill in multi-gang switch/receptacle applications.
  • FiberglassBox™ Series: Part of Allied Moulded's FiberglassBox™ product family, purpose-built for residential and receptacle wiring device installations.
  • New-Work Installation: Designed for new-work electrical rough-in per manufacturer installation guidance.

Allied Moulded 2302-NK – Frequently Asked Questions

1) What is the difference between the Allied Moulded 2302-NK and 3300-NK switch boxes?
Gang count. The 2302-NK is the 2-gang box and the 3300-NK is the 3-gang, and both are molded from the same fiberglass reinforced thermoset polyester in the FiberglassBox series. Pick by how many wiring devices land in that opening: two switches or receptacles side by side takes the 2302-NK, three takes the 3300-NK. Interior volume scales with the gang count.
2) Can I use an Allied Moulded FiberglassBox multi-gang box in an existing finished wall?
No. These are new-work boxes, meant to be fastened to framing during rough-in before drywall goes up. For cut-in work in a finished wall you need an old-work (remodel) box that clamps to the drywall instead.
3) How deep a wall cavity do I need for the Allied Moulded FiberglassBox 2-gang and 3-gang switch boxes?
The published height for these boxes is 3-3/4 inches, and each gang configuration is sized for standard wall cavity depths in new construction and remodel framing. In practice that means standard 2x4 stud framing accepts them without furring.
4) Why choose a fiberglass switch box over a steel or PVC box?
Corrosion is the main reason. Fiberglass reinforced thermoset polyester will not rust the way stamped sheet metal does in damp or chemically aggressive locations, and it is rigid rather than flexible, so it resists cracking and warping better than standard plastic boxes. That rigidity also holds the box square through drywall and finish work, which keeps device faces where you set them. Steel is still the choice where you need a metallic raceway ground path through the box.
5) Will a standard 2-gang or 3-gang cover plate fit the Allied Moulded 2302-NK and 3300-NK?
These are standard-gang wiring device boxes, so a 2-gang plate suits the 2302-NK and a 3-gang plate the 3300-NK, in whatever style matches the rest of the openings. Plates and devices are ordered separately from the box.
6) Are Allied Moulded FiberglassBox switch boxes made in the USA?
Yes, the FiberglassBox multi-gang switch boxes are of United States origin, which matters on public and institutional jobs carrying domestic-content requirements.
7) Is the Allied Moulded FiberglassBox suitable for light commercial work or just houses?
Both. The FiberglassBox series switch boxes are built for residential and light commercial wiring, typically switch and receptacle rough-in on new construction and remodels. For heavy industrial raceway systems, a cast or steel box is the usual specification.
8) Where do I find the box volume and cubic inch fill rating for the 2302-NK and 3300-NK?
Allied Moulded publishes the per-model figures on the FiberglassBox spec sheet supplied with these boxes; interior capacity scales with gang count, so the 3-gang 3300-NK carries more volume than the 2-gang 2302-NK. Use that sheet's cubic inch value when you run your conductor and device fill calculation.
