I'm replacing an old ceiling fan. The old one wobbled a lot even after tightening the blades and trying to balance it. Right now the electrical box is just a plastic one that appears to be screwed into the ceiling joist. Will replacing the box with a brace like this one help with the wobbling?
Here is a picture of what the old fan was attached to. I haven't taken off the old fan bracket yet.
I'm not sure what happened to the ceiling where the fan touched it. It looks like it melted or they installed the fan when the paint was still wet.
So when I took the metal piece off the electrical box fell down. Looks like there is already a brace there.
