Orbit FSDB-FB 4" Fan Support Deep Box with FB Bracket

The Orbit FSDB-FB is a 4" fan support deep box engineered to provide a secure, code-compliant mounting point for ceiling-mounted fans, fixtures, and outlet boxes. Built to a 2-1/8" deep profile, this 4" octagon ceiling box gives installers the extra interior volume needed for wiring devices, fan-rated hardware, and conductor fill in applications where a standard shallow box will not accommodate the required components. The box ships complete with an integrated FB bracket, which provides a rigid attachment interface to framing members for a stable, wobble-free installation — an important consideration for any box that will ultimately support the ongoing dynamic load of a rotating ceiling fan. Whether the application is new residential construction, a remodel, or a commercial ceiling assembly, the FSDB-FB is sized and configured to deliver a dependable foundation for fan or fixture support.

Orbit FSDB-FB – Frequently Asked Questions

1) Is the Orbit FSDB-FB box rated to support a ceiling fan, or only a light fixture?
The FSDB-FB is built as a fan support box, not just a fixture box. It comes with an FB bracket factory-installed, which attaches to framing members to carry the ongoing dynamic load of a rotating ceiling fan. It will also serve a standard ceiling fixture or outlet application, so one box covers both on a job where the ceiling use may change later.
2) How deep is the Orbit FSDB-FB ceiling box, and why order a deep box instead of a shallow one?
It is a 2-1/8 inch deep body on a 4 inch octagon footprint. The extra interior volume matters when you are stacking a fan-rated mounting hardware kit, wiring devices, and several conductors in the same box, where a shallow ceiling box runs out of room for the required fill.
3) Is the FB bracket on the Orbit FSDB-FB for new framing or for retrofitting into a finished ceiling?
The FB bracket is a rigid bracket that fastens to framing members, which means you want access to the joists, so it suits new residential construction and open-ceiling commercial work, plus remodel work where the ceiling is opened up. For a cut-in retrofit into an intact finished ceiling you would be looking at a different style of support, since this one needs to land on framing.
4) What is the difference between the Orbit FSDB-FB fan support box and the Allied Moulded 9304 ceiling support box?
Both are ceiling support boxes, but they differ in construction and bracketing. The Orbit FSDB-FB is a 4 inch octagon box with a 2-1/8 inch deep body and a factory-included FB bracket that attaches to framing members, and it is configured specifically as a fan support box for the dynamic load of a rotating ceiling fan. The Allied Moulded 9304 is a fiberglass reinforced ceiling fixture support box from the FiberglassBox series, so it is a non-metallic body rather than a bracketed box with a stated 2-1/8 inch depth. If the ceiling assembly calls for a non-metallic box, the 9304 is the one to look at; if the job needs the deep profile and rigid framing attachment for a fan, the FSDB-FB is configured for that.
5) Will a standard ceiling fan canopy cover the Orbit FSDB-FB box?
Yes. The 4 inch octagon shape is the common ceiling outlet footprint, so standard ceiling fixture and fan-rated cover plates and canopies fit over it. Nothing special is needed on the trim side.
6) Does the Orbit FSDB-FB come as a single box or in a case quantity?
It ships as a pack of 100 boxes, each with its FB bracket already attached. That quantity suits a multi-family or tract build where every bedroom and living space gets a fan-rated ceiling outlet; it is a lot of box for a single-fan service call.
7) What is the Orbit part number for the 4 inch deep fan support box with the bracket?
Order Orbit FSDB-FB. The FSDB part of the designation is the fan support deep box and the FB suffix is the bracket, so a box ordered without that suffix will not include the framing bracket.
8) Will the Allied Moulded 9304 work as a drop-in replacement for an Orbit FSDB-FB?
Treat them as alternatives rather than drop-in equivalents. The Orbit FSDB-FB arrives as a 4 inch octagon box, 2-1/8 inch deep, with an integrated FB bracket that fastens to framing, which is what gives it its fan support configuration. The Allied Moulded 9304 is a fiberglass reinforced ceiling fixture support box, a different construction and mounting approach. Verify the box depth you need for conductor fill and the way the box will attach to the framing in your ceiling before substituting one for the other.
