Allied Moulded 9345 PVC 1-Gang Raised Plaster Ring, 4-Inch x 4-Inch x 1/2-Inch, FiberglassBox™

The Allied Moulded 9345 is a 1-gang raised plaster ring built from durable PVC as part of the FiberglassBox™ product line. Sized at 4-Inch x 4-Inch x 1/2-Inch with a 4.2-cubic-inch interior volume, this plaster ring is engineered to bring device boxes flush with finished plaster or drywall surfaces, giving electrical contractors a clean, code-friendly mounting surface for single-gang devices in commercial and residential wall assemblies. As a PVC component, the 9345 resists corrosion, moisture, and the chemical exposure that can degrade metallic ring products over time, making it a reliable choice anywhere long-term durability matters. Its raised profile is specifically designed to extend a recessed box outward to match plaster or wallboard thickness, ensuring devices such as switches and receptacles sit properly within the finished wall plane. The 1-gang configuration keeps the footprint compact for single-device applications, while the FiberglassBox™ family pairing supports consistent fit and finish when used alongside compatible Allied Moulded enclosures.

Allied Moulded 9345 – Frequently Asked Questions

1) What does the Allied Moulded 9345 plaster ring actually do on a wall box?
The 9345 is a 1-gang raised plaster ring that mounts on the front of a recessed device box and extends it out to the finished wall plane. It carries a 1/2 inch raise, so it takes up the thickness of plaster or wallboard and lets a switch or receptacle sit flush in the finished surface instead of buried behind it. Overall size is 4 x 4 x 1/2 inches.
2) Will the 9345 fit a standard 4 inch square box?
Yes. The ring measures 4 x 4 inches across the face, which is the standard 4 inch square box footprint, and it reduces that opening down to a single-gang device opening. Model number to order is 9345.
3) Do I need a 1/2 inch raised ring or a deeper one for my drywall?
Pick the raise to match your finish thickness. The 9345 carries a 1/2 inch raise, which suits 1/2 inch drywall or a comparable plaster coat. If you are running 5/8 inch board or double-layer drywall, a 1/2 inch ring leaves the device set back and you want a deeper raised ring instead. The device yoke must land within the finished plane.
4) How much does the 9345 plaster ring add to box fill calculations?
The ring adds 4.2 cubic inches of volume, which counts toward the box fill total for the device opening. That is the figure to add to your box's cubic inch capacity when you run the conductor count for the single-gang device.
5) Is the 9345 ring metal or plastic, and does it hold up in a damp wall cavity?
It is molded PVC, not steel. That is the reason to pick it in wall cavities that see moisture or chemical exposure, where a steel ring corrodes over time. It is nonmetallic, so it does not serve as any part of an equipment grounding path.
6) Does the Allied Moulded 9345 work with Allied Moulded fiberglass boxes?
Yes, the 9345 is part of the FiberglassBox line and is built to pair with Allied Moulded FiberglassBox enclosures for a matching fit at the device opening.
7) Can I use the 9345 for a two-gang switch bank?
No. It is a 1-gang ring, so it opens for one device only, a single switch or a single receptacle. A two-device bank needs a 2-gang ring on a 4-11/16 or double-gang box.
8) Is the 9345 usable on a remodel where the box is already set back in the wall?
That is exactly the case it covers. The raised ring extends a recessed box outward to meet the plaster or wallboard face, which is common on renovation work where an existing box sits behind a new finish layer. It works on new construction the same way.
