Mount ceiling fan without changing box?
 
Hi;
I want to replace a standard light fixture with a ceiling fan. Thinking that it will be difficult to get up into the attic to access the box, and install the correct support, I thought perhaps there is an "external" support method that would not require the current electrical box to be replaced.

What I am thinking of, is an aluminum plate/bar of sufficient thickness and dimensions, with a hole in the center for attachment to the current box.
Once attached to the box, the plate would then be secured to the joists with long screws that would hold it against the plaster/sheetrock ceiling and secured with the screws to the joists.

Perhaps this would not be the most elegant method, but it seems to me that it would work, and should be ok with code, as it would still be attached to the electrical box.

All of this aside, I am aware of the normal method of using a box with a ratcheting support beam that can be installed through the standard cutout in the ceiling.

Does such a thing that I am talking about exist?

Thanks

FW

Edit: Googling on this reveals that there is no such plate that I am referring to, but a method of supporting the box by using a large piece of plywood screwed to the ceiling joists, with the box properly mounted to it.
So I guess I will just use the ratcheting support, or go into the attic and gain access. The issue here is that there is a lot of stuff that will have to be moved in the attic to get to the floor area where the fixture is located.

Never seen anything like what you're talking about.

Actually, it was something I dreamed up (literally; it came to me in a dream).
I dread having to go into the attic and remove the floor. It's my brother's house, and he has a lot of stuff up there that will have to be moved.
At least the floor is plywood, not tongue & groove, so it's just a matter of unscrewing the screws (I hope he screwed it down, not nailed it) that hold it to the joists.
But my first choice would be to use the box with the ratcheting support beam.
It is also possible that the box that is already installed will support the fan. I won't know until I remove the light fixture and inspect it.

They make fan supports that do not require you enter the attic but you do need to remove the existing box to install them. Check your local hardware store and they will have them.

Are you referring to those telescoping ones with two arms? All the ones I've used of that type require you to fasten them to the adjacent joists in a way I can't imagine doing without opening the ceiling or having attic access.

Is there a clamp or threaded rod type design I'm not familiar with?

There is a threaded rod type that you clamp the box to the rod after installation.

Ahhh. Savvy now.

Turned out to be easier than I thought.
There was already a metallic box in the ceiling, and it was screwed to a joist which was directly above it. I only needed to replace the screws with larger/longer ones.
The fan was small, and not very heavy. It is securely mounted, and working great!
For once, a job turned out easier than anticipated!
