ceiling fan box raised 1/4" from ceiling and will cause fan wobble.

I am installing a ceiling fan in my master bedroom. The center of the room just so happens to be dead on a joist.

I just a 4" round whole and secured a 1/2in shallow depth box.

It turns out that the ceiling sheetrock is only 3/8" so the box is raised from the ceiling about a 1/4 inch, which isn't good.

Does anyone know if they make a 1/4 inch box? If they don't how would I go about installing the ceiling fan?

Thanks

You could notch the joist one quarter inch. That shouldn't cause a structural problem.

Attach the fan mount to the box. Even if there is a small gap between the canopy and ceiling it will look fine. In fact many fan manufactures add rubber spacers to keep the canopy off the rock to prevent the transmission of noise.

BTW - 1/2 pan -3/8 rock = 1/8"

1/4" makes no difference in the installation of the fan. The bell will cover the shallow box completely. Now you mentioned wobble. How is this box attached to the framing??? How many points of attachment and what method.

Thanks for all of these great replies.

I just went an measured, it is sticking out a little under a quarter inch, the box was a little bigger then a half inch (5/8?) even though it said it was half.

I really don't want to get involved in notching the joist. I can put the canopy over it but even with the ring, it does not sit flush with the ceiling. This gap won't cause any issues? Visually I don't think you will notice it from the floor.

I did not try to install the fan since I thought it was going to wobble, sorry if I was miss leading. I followed the box's directions and used all 4 points of connection to the joist.

Thank you all for your very helpful replies!

Why not use a medallion to make up the difference? When I installed the ceiling fan in my living rm I had to make up close to 1.5" so I made 2 medallions out of wood [1 smaller than the other], routed the edges [hole cut in the centers] and then caulked and painted it with white enamel. It looks nice and took care of the gap.

As long as the fan is securely mounted to the box and the box is securely mounted to the framing the fan should not wobble. (balancing might be required.)

Is the box fan rated? I would hate to see a fan fall on someone's head.

@Justin Smith thank you for your concern, yes the box is fan rated to 70 lbs.

I just wanted to thank everyone for their input on this. Even though there was a quarter in space I went ahead and installed the ceiling fan to see how it would look. After the canopy cover and ring were installed there was less then an 1/8" space which isn't noticeable. There is absolutely no wobble in the fan (which was my original concern.)

Again, thank you all for your help. Hopefully this thread will help someone in the future.
