Steel City 56111 CFB Round Ceiling Fan Box, Steel, 4 In, 6 in³

It measures 4 inches in diameter with a 1/2 inch depth, and the box volume is 6 cubic inches. The shallow depth is what makes it suited to a pan-style ceiling application where there is little room above the finished ceiling. Use the 6 cubic inch figure when you run your box fill calculation for the conductors, device and clamps landing in it.

No. A drawn 4 inch steel pan like the 56111 CFB is intended to be fastened to framing, which means access to the joist. For a remodel where you only have the hole in the drywall, use a listed retrofit fan support assembly instead, such as the Allied Moulded SB-CB Sliderbox or the Pass & Seymour Reiker drop ceiling fan and fixture support box.

The RACO 295-1 is the nearest match in steel: a 4 inch round fan-rated ceiling pan in the THE INSIDER series. Like the Steel City 56111 CFB, it is a 4 inch round steel fan-support box, so both land in the same 4 inch round ceiling opening. The 56111 CFB is a drawn steel box with 6 cubic inches of volume and 1/2 inch depth, so compare the available box volume against the number of conductors and the fan canopy you are wiring before swapping one for the other.

Yes. The Allied Moulded 9304 is a fiberglass reinforced ceiling fixture support box, and the Allied Moulded SB-CB Sliderbox is a polycarbonate ceiling fixture support box. Both are nonmetallic where the 56111 CFB is steel, which matters if you are running nonmetallic cable and want to avoid a separate bonding connection to a metal box, or if the box sits in a damp or corrosive location. The 56111 CFB is steel and carries a UL listing under E2969.

The Steel City 56111 CFB is a 4 inch round drawn steel box with 6 cubic inches of volume at 1/2 inch depth, which is tight once you have fan leads, supply conductors and a ground in the box. If you need more room, look at a deeper nonmetallic support box such as the Allied Moulded 9304 fiberglass reinforced ceiling fixture support box or the Allied Moulded PC244OW FlexBox ceiling fixture support box, both of which are built as fixture support boxes rather than shallow pans. Confirm the box volume against your conductor count before you commit.

Only if the replacement is fan-rated. The 56111 CFB is a steel ceiling fan box, and a general purpose 4 inch round pan of the same size is not interchangeable because it is not rated to carry a fan's weight and torque. Among fan-rated steel options, the RACO 295-1 is a round fan-rated ceiling pan, 4 in., steel, in THE INSIDER series. Match on the fan rating first, then on the 4 inch round footprint and the box volume.

6 cubic inches is tight. At 6 cubic inches, a shallow 4 inch pan like the 56111 CFB suits a simple feed to the fan, not a box where multiple circuits are being spliced. If you have several cables plus a separate fan and light switch leg, step up to a deeper fan box, such as the RACO 295-1 round fan-rated ceiling pan or an Allied Moulded 9304 fiberglass fixture support box.

Steel, silver in color and drawn in one piece. Because it is metallic, the box itself must be bonded to the equipment grounding conductor, and it can serve as the grounding path for metal raceway. If your install calls for a non-metallic box instead, the Allied Moulded SB-CB is a polycarbonate ceiling fixture support box and the ALM-9304 is fiberglass reinforced.

The 56111 CFB is furnished with 1/2 inch knockouts, so it accepts 1/2 inch trade size NM cable connectors, EMT or flex connectors. That is the standard size for a 14/2 or 12/2 branch circuit feeding a fan.

The Steel City 56111 CFB is a fixed 4 inch round drawn steel ceiling fan box with 1/2 inch depth, so it mounts where you anchor it with no lateral adjustment. If you need to slide the box to center the fan between joists, the Allied Moulded SB-CB Sliderbox polycarbonate ceiling fixture support box and the Allied Moulded PC244OW FlexBox ceiling fixture support box are built around adjustable support, which is the difference that matters on a retrofit where the fan location is already set by the room.

It is sold each, so you order one per fan location rather than by carton.
