There are 2 ways that I know of, neither of which I have personally done.
I need to install about a dozen ceiling fans into a suspended ceiling. The tiles are 24x48
Should I mount the box to the joists and drop a fan pole through the tile.
Should I "hang" a box ( Arlington FBRS420SC-1 ) from the joist and mount the fan directly to it?
I like the idea of the Arlington box, any one do this before and have a preference over the 2 methods?
Here is the kicker, the roof slopes towards the rear of the building and I would have to account for the drop in height if I use the "pole" method. If I use the Arlington box then all fans would be uniform without much thought.
