RACO RACO299 – Frequently Asked Questions

1) Will a RACO 299 ceiling box fit a standard 4 inch round fixture canopy and pancake-style light?
The RACO 299 is a 4 inch round steel box sized to standard ceiling fixture outlets, so the usual 4 inch round fixture canopies and mounting straps line up with it. It is 2-1/8 inches deep, which is a full-depth box rather than a shallow pancake, so plan on a ceiling cavity or joist bay that can take that depth.
2) How many cable or conduit runs can I bring into the RACO 299 round ceiling box?
There are five 1/2 inch knockouts on the 299, placed for entry from several directions. That covers a feed plus switch legs or a through-run on a multi-fixture circuit, and the 1/2 inch size takes standard 1/2 inch conduit fittings and cable connectors.
3) Can I use the RACO 299 to hang a ceiling fan?
Treat the 299 as a standard ceiling outlet box for lighting fixtures and general rough-in, not as a fan-rated box. Ceiling fans require a box specifically marked as fan-rated or a fan support brace; pick one of those if a paddle fan is going on the opening.
4) Does the 2-1/8 inch depth of the RACO 299 give me enough box fill for several splices?
A 4 inch round box at 2-1/8 inches deep is the deeper of the two common round depths, so it carries more cubic-inch capacity than a shallow round box for splices, fixture leads, and device terminations. If you are stacking several cables plus grounds and a fixture whip, that extra depth is the reason to choose the 299 over a pancake or 1/2 inch deep round.
5) Is the RACO 299 steel or plastic, and does that matter for grounding?
It is steel. A steel box gets bonded as part of the equipment grounding path, which is why electricians reach for it on conduit runs and in commercial work where a nonmetallic box would not carry the bond.
6) Can the RACO 299 be used on a remodel or retrofit, or is it new-construction only?
Both. The 299 works as a ceiling outlet box in new-construction rough-in and in remodel or retrofit wiring, with the five 1/2 inch knockouts giving cable and conduit entry from whichever direction the existing run comes from.
