Do they make a ceiling fan mounting box that mounts to a drop ceiling? (grid with tiles). Going in a lobby in a Doctors office. I heard they make a kit with a chain that holds it, but don't know the brand.

Look at the catalog above. They have support that hangs from the structure above and at the same time sits on the tee grid for horizontal stability.

Here is another

Fan/Fixture Box Kit for Suspended Ceilings

Pass and Seymour is also making one. Arlington may have added one to their line also.

The Arlington design is from me....

I gave it to Rex Moore some two years ago....

It was MY idea to use turnbuckles to solve a soft lid HEAVY pendant lighting situation in Grass Valley, California.

Weird, that Arlington quotes my Rex Moore buddy inre the time saved.

They don't deserve any patent since such an install is already 26 months old.

As for myself, impossible for me to receive $$$ for my idea. I'm not a manufacturing engineer.

BTW, my current employeer wanted to know why I wanted turnbuckles for just such an application -- recently -- and the very next day EC Mag shows the Arlington Ad.
