Centaur CM-FSB-NBH-CP – Frequently Asked Questions

1) Will a Centaur 4 inch round fan support box hold a ceiling fan, or is it only for light fixtures?
The Centaur 4 inch round box is built for fan support. It is a fan-rated box with an integrated mounting brace, and Centaur lists the application as supporting ceiling fans in residential and commercial installations. It also works for standard light fixtures, so it is a safe choice on an opening where the owner may swap a fixture for a fan later.
2) What is the difference between the With Brace and New Work Bar Hanger versions of the Centaur fan support box?
Both are 4 inch round fan support boxes; the difference is how they attach. The With Brace version uses a V-brace that spans between joists, which is what you want when you are locating the box between framing members. The New Work Bar Hanger version comes as a contractor pack with a pre-installed non-metallic bracket, meant for nailing off to framing during new construction rough-in. Neither is a retrofit box for a finished ceiling.
3) Can I use the Centaur fan support box in a remodel where the ceiling is already closed up?
No. These are new-work boxes. The brace and bar hanger versions both need access to the framing, so they go in before the drywall or in a renovation where the ceiling is open. For a finished ceiling you need an old-work retrofit fan brace that installs through the existing box hole.
4) Do Centaur 4 inch fan support boxes come in bulk for a multi-unit job?
Yes. The New Work Bar Hanger version is sold as a contractor pack, and Centaur offers the 4 inch fan support box in 20-count quantities, which is how most multi-family and tract work buys them.
5) Is the Centaur fan support box round or octagonal, and will a standard fan canopy cover it?
Centaur lists the shape as round / octagonal in the 4 inch size, which is the standard 4 inch ceiling box footprint that fan canopies and fixture canopies are built to cover.
6) Will a Centaur fan support box corrode in a damp location like a covered porch ceiling?
Centaur builds these 4 inch fan support boxes from non-corrosive material, and the bar hanger version uses a non-metallic bracket, so rust is not the failure mode. Note that the box itself is not described as a wet or damp location enclosure, so match the fan or fixture rating and the ceiling assembly to the location.
