Install Ceiling Fan on Studs

Hi,

I have a question about ceiling fan installation (a heavy one)

When I removed the old light fixture I realized that the electrical box was screwed only from one side. Not quite good to install my ceiling fan.

The ceiling is new in an old building, I looked by the hole and saw that the original joists are separated by 36 inches and that new joists were screwed at the bottom of it. Then wood studs were screwed perpendicularly. The electrical box was screwed on one of it.

Here is a picture :

I thought about a fan brace but the studs are only 1.6 inches high and I don't know if the studs can support the weight ? (and vibrations ?)

Thank you for your help,
Francis

Welcome to the forums.

Since you have attic access.... add your own fan framing.

Hi PJmax,

Thank you for your answer, unfortunately I don't have access, I just illustrate the positions of joists and studs from what I see by the hole of the old light fixture.

Do you think I have to enlarge the hole to place a wood frame then cover the hole with a medallion ?

Just use an old work fan box that installs from below.

Or use a Smart fan box: http://www.homedepot.com/p/Madison-E...BFAN/203343431

His problem Ray looks like his 2x4's are on the flat.... almost like furring strips.

If that is a 2x4 on the flat then you could probably use a fan rated pancake box. You would move the hole so that the pancake box would be on the wood's surface. May require some slight patching.



When you say heavy...... how heavy is that ?
You may need more fasteners into the wood other than the box screws.

Thank you for your answers.

You're right, 2x4' are on the flat and I can really use your solution then hiding the enlarged hole with a medaillon.

It's not particulary heavy but more than my old light fixture

Do you think that the 2x4 can support the weight of a regular 52 inches fan ceiling (I don't know if these 2x4 are screwed or nailed to the joists) ?

That and the other question is..... is it fastened at every joist.

If it was me.... I'd locate the joist at either end..... predrill with small bit and add two 3" screws at each joist for a total of four screws.

Sounds really good !
Screwing through the drywall the 2x4 and the joist together at each ends, then I can put some spackling paste to fill holes.

Thank very much for your help, thank you Ray too.

Regards,
Francis
