Allied Moulded 4304-NK – Frequently Asked Questions

1) How many devices will the Allied Moulded 4304-NK box hold?
It's a 4-gang box, so it takes four switches, four receptacles, or any mix of the two in one enclosure. Overall footprint is 7-1/2 x 3-3/4 x 3-9/16 inches, which is what you need to confirm against your stud bay and drywall cutout before rough-in.
2) Is 75 cubic inches enough for four devices and the conductors in a 4-gang box?
The 4304-NK gives 75 cubic inches of usable volume, which is what you work your NEC box fill against: each device counts as two conductor volumes plus the conductors, clamps and grounds landing in the box. At 75 cubic inches there is room for four devices with 12 AWG homeruns and travelers in most residential multi-gang switch banks. Add up your fill for the actual circuit count before you commit.
3) Why use a fiberglass box instead of a metal or PVC switch box?
The 4304-NK is molded from fiberglass reinforced thermoset polyester. It's non-metallic, so no bonding of the box itself and no corrosion in damp framing or coastal jobs, and thermoset holds its shape rather than softening or flexing the way thinner PVC can when you torque device screws into a four-gang bank. If you need a box you can bond and use with metal-clad or EMT terminations, that's a metal box job, not this one.
4) Is the Allied Moulded 4304-NK a new-work box or an old-work remodel box?
It is set up for rough-in on new construction and remodel wiring, mounted to framing before drywall goes on. If you are cutting into finished drywall with no accessible stud, you want an old-work or retrofit style box with wing clamps instead.
5) Can I standardize on the 4304-NK across a multi-family or apartment build?
Yes, for switch and receptacle rough-in it works as a standard 4-gang. Same part number every opening means the same 75 cubic inch fill calculation, the same 7-1/2 x 3-3/4 x 3-9/16 inch cutout and the same 4-gang plates for the whole property, which is the main reason crews spec one box across a build. It is a residential switch and receptacle box, so distribution, low-voltage, and wet-location openings still need their own enclosures.
6) What is the exact part number to order this 4-gang Allied Moulded fiberglass box?
Order it as Allied Moulded 4304-NK, from the FiberglassBox line. That's the manufacturer part number on the box itself, so it's what to put on a purchase order or hand to a counter.
7) Where can I get the manufacturer spec sheet for the Allied Moulded 4304-NK?
Allied Moulded publishes a PDF spec sheet for the 4304-NK that carries the printed dimensional and capacity data, useful when an inspector or a submittal package wants manufacturer documentation rather than a catalog page.
