said by whizkid3:This is poor advice. Using a box that is not rated for a ceiling fan is not code-compliant anywhere the NEC is used (everywhere in the USA). Fans installed with 'any metal box' have ripped out and injured people as well as started fires.
Yup, nothing like hanging a spinning guillotine from a couple of tabs that only engage maybe 3 threads of the anchoring screws total.
If one is lucky when it comes down it will land on the coffee table mixing the adult beverages with the popcorn and scattering them to and fro, tripping a breaker in the process, putting the room into total darkness past the flash and ruining a Netflix evening with the OL.
Later on after the popcorn from the table and the ceiling has been vacuumed up and while she trying to salvage the carpeting from the red wine stains, (a bottle she bought), one can hang in the garage setting up a cot or a sleeping bag and ponder the savings and ease of using just any box.
