Two summers ago, Cara's dad replaced the ceiling fan in our living room with a shinier, beefier one. The original ceiling fan hadn't been particularly well hung - it was installed with a plastic circuit box that was wired (meaning, as a support mechanism) with copper wire to a pipe running above the ceiling. Lovely. So he got a ceiling fan support kit, with an expandable support bar that jams in between joists so that you can stably hang a fan from it.

As our tv room rock band room's ceiling fan was looking similarly questionable in its structural integrity, I decided it needed to be rehung. Went out and got a support bar and everything.
