Before installing a ceiling fan, electrical code requires that you use a fan-rated outlet box that will support the extra weight and the motion associated with a fan. A fan-rated box will be labeled as such inside and typically can support up to 70 lb.

Obviously when it was installed by builder didn't think to attach it properly to the joists, so that something I'll do on my own. Any tips on removal of the old box?
