Hanging ceiling fans.
Just got a call from nursing home to install ten ceiling fans in their hallways, all drop ceilings. Someone else had installed some before, fans were mounted to a 2x4 sitting on tile. I informed that that we had to hang the new fans more securely. I planned on threaded rod, from either beams or strut. Do you think 1/4 rod enough or should I use 3/8?

24" is a bit long unless you have stabilizer bars at the grid. Also, be sure the ceiling wires are plentiful if you decide to hang them from the grid.

Hanging a fan from just the grid bars is NOT an option.

That does not make it compliant. I say a ceiling fan hung from a pop in box and it lasted for years-- so what.

I think that the plywood installation is the most secure method.
A piece of plywood 2x2 or 2x4, layed right on top of the tile. There is about 1/2" of grid above the tile and the ply sits snugly. Screw it to the grid if you are so inclined. Bolt a fan/pan thru the ply and throw on a support wire to stay legal.
That space is designed to hold a troffer, it will hold a fan.

Plywood lacks grid clips like a troffer would be the only problem I see

I know about code compliant.. but if I can put (4) layin fixtures in a ceiling without any problem with the amount of weight.. then a ceiling fan should have no problem being supported by the same grid using the right hardware..

With a fan the weight is in one spot but with troffers the weight is dispersed.

No just trying to get you to give compliant info. Anyone can offer non compliant means.

You have to support and clip the troffer too. Whats the difference?
