I am about to install a ceiling fan where there was only a simple light fixture before.
The existing electrical box will be removed, and I will install this box in its place. This has me attaching the box directly to a single joist in the ceiling.
I am not planning to use a brace to suspend the box between two joists. This is a relatively modern house from the 70s and the ceiling appears to be in good condition. I am wondering do I need to reinforce the joists at all or is this sufficient to hang a ceiling fan of average weight?
