Allied Moulded 9312-EWK 2-Gang Fiberglass Reinforced Thermoset Polyester Electrical Switch Box

The Allied Moulded 9312-EWK is a 2-Gang Residential/Receptacle Electrical Switch Box built from Fiberglass Reinforced Thermoset Polyester as part of Allied Moulded's FiberglassBox™ line. Measuring 4-1/8-Inch x 3-1/4-Inch x 2-3/4-Inch with a 28-Cubic-Inch interior capacity, this box is engineered to house two-gang switch or receptacle devices in residential wiring applications. The fiberglass-reinforced thermoset polyester construction offers a durable, non-metallic alternative to traditional steel boxes, making it well-suited for standard residential branch-circuit installations where a lightweight, corrosion-resistant enclosure is preferred.

  • Box Dimensions: 4-1/8-Inch x 3-1/4-Inch x 2-3/4-Inch, sized to accommodate 2-gang device installations in standard wall openings.
  • Interior Capacity: 28-Cubic-Inch volume, providing adequate fill space for two-gang switch or receptacle wiring configurations per code-driven box-fill requirements.
  • Durable Construction: Fiberglass Reinforced Thermoset Polyester material resists corrosion and does not conduct electricity, offering long-term durability compared to metallic box alternatives.
  • 2-Gang Configuration: Designed specifically for Residential/Receptacle applications requiring two devices side by side, such as paired switches or a switch-and-receptacle combination.

Allied Moulded 9312-EWK – Frequently Asked Questions

1) Is the Allied Moulded 9312-EWK box big enough for two devices plus the wiring?
The 9312-EWK is a 2-gang box with 28 cubic inches of interior volume, which is the number you run your box-fill calculation against for two switches, two receptacles, or a switch-and-receptacle pair. Outside dimensions are 4-1/8 x 3-1/4 x 2-3/4 inches.
2) Should I use a fiberglass box like the 9312-EWK or a steel box?
Fiberglass reinforced thermoset polyester, which is what the 9312-EWK is moulded from, doesn't conduct and doesn't corrode, so it's the choice where a metal box would rust or where you don't want to bond the box itself. A steel box is what you go to when the installation calls for a metallic raceway system terminating at the box. For residential branch-circuit rough-in with non-metallic cable, the fiberglass box does the job.
3) Will the Allied Moulded 9312-EWK work for a remodel cut-in, or is it new construction only?
It's a rough-in box for new construction wall framing, per the stated application. For an existing finished wall you want an old-work / retrofit box with wing clamps instead.
4) Can I gang two of these 9312-EWK boxes together to get a 4-gang opening?
No. The 9312-EWK is moulded as a fixed 2-gang enclosure, not a sectional steel box with removable sides, so it cannot be ganged. If you need three or four devices side by side, order the box in that gang size to begin with.
5) Will a standard 2-gang cover plate fit the Allied Moulded 9312-EWK?
Yes. It's built to a 2-gang device pattern for two switches or receptacles side by side, so standard two-gang device plates line up with the mounting screws.
6) Where can I get the manufacturer spec sheet for the 9312-EWK?
Allied Moulded publishes a spec sheet for the 9312-EWK, linked in the product's technical data at media.distributordatasolutions.com under the Allied Moulded document library.
