The Allied Moulded SB-CBFR is a Sliderbox® ceiling fan/fixture support box engineered from durable polycarbonate for reliable overhead mounting of ceiling fans and light fixtures. Measuring 4-Inch x 2-3/4-Inch with a generous 25-Cubic-Inch interior capacity, this support box gives installers ample room for wiring connections while providing a solid, code-conscious mounting platform.

  • Generous Interior Volume: A 25-Cubic-Inch capacity provides ample room for wire splices, connectors, and fixture hardware inside the box.

  • Fixture-Ready Support: Specifically configured as a ceiling fan/fixture support box, giving installers a dedicated solution rather than adapting a general-purpose box.

Allied Moulded SB-CBFR – Frequently Asked Questions

1) How much wire volume does the Allied Moulded SB-CBFR ceiling fan box give me?
The SB-CBFR Sliderbox gives you 25 cubic inches of interior volume in a 4 x 2-3/4 inch box. That is enough room to land the fan's supply conductors, grounds and wire nuts without fighting the splices back into the box when you push the canopy up. If your box fill calculation is running past 25 cubic inches, step up rather than force it.
2) Is the SB-CBFR rated to hang a ceiling fan, or just a light fixture?
It is built as a ceiling fan/fixture support box, so it is a dedicated fan-rated box rather than a general purpose round box you would be adapting. That means you can use it for a paddle fan or for a standard light fixture. A plain non-metallic outlet box is not a substitute for fan support.
3) Is this a metal or plastic ceiling fan box?
Non-metallic. The SB-CBFR is molded polycarbonate, so it will not rust or oxidize the way a steel pan box can, and the housing itself is non-conductive. That makes it a reasonable pick for damp or corrosive interior spaces where a steel box would be the first thing to go.
4) Can I use the Allied Moulded SB-CBFR in a remodel, or is it new construction only?
Both. Allied Moulded lists the SB-CBFR for new construction and remodel ceiling box work, in residential and light commercial installs. The deciding factor on your ceiling is the mounting condition you have available, not the box itself.
5) Will the SB-CBFR fit between standard ceiling joists?
The box body is 4 x 2-3/4 inches, a compact footprint meant to drop into standard ceiling joist and fixture mounting locations without extra bulk. Check your 2-3/4 inch depth against the ceiling cavity you are working in before you commit.
6) What part number do I order for the Allied Moulded Sliderbox ceiling fan box?
