How To Remove Ceiling Junction Box From Below
- #iii
I've mainly washed commercial and industrial work before, but am starting to do some residential now, too. A few days ago I was replacing a ceiling lite fixture with a ceiling fan. This was on the first floor of a 2 story house, so no access from above - only from beneath. It was a textured sheetrock ceiling. The existing ceiling box was a 4" round brown plastic box (with only 8-32 screws) that was nailed to the ceiling joist with two nails exterior the box (the standard blazon, with the molded supports/nails outside the box at almost 45 deg. to the box). I had a hard time getting the existing box out of the ceiling from below -- I finally clipped the box apart using my diagonal cutters (dikes) a piece at a time until I could get to the nails. At that place must exist an easier way!!! How exercise you guys do it??? I'chiliad sure I'll run across this situation a lot, and I desire to make a much easier job of it in the future!!!
Later I finally got the existing box out, I installed (from below) one of the steel fan boxes (with ten-32 screws) with the screw-out type bar hanger that extends to "seize with teeth" into the wood joists on each side. It seemed pretty solid. I retrieve information technology was a Steel Metropolis model, but I'm not certain about that. Is there something better and easier to use?
Thank you for the help!!!
you've pretty much got it.
trounce the erstwhile one out with a screwdriver and dykes.
pull out the nails.
screw in a spreader bar with box.
rister came out with them a long time ago,
and now there are cheap knockoffs. the rister was
well made.

tx2step, I think yous accept the procedure mastered. Aye cut autonomously with your dykes, Linemans, hammer, large screwdriver the quondam box. Then y'all did simply as I have done, install the adjustable fan subclass. Steel City & Reiker both take a version. At that place isn't really any short cutting. If you lot need a fourteen-3 Romex at the box, take upward the carpet above & cut the sub floor

If the box is nailed to a joist you don't need to modify information technology, you are allowed to back up the fan independently from the box. A couple of good screws through the fan backplate and your set.

There are remodel fan boxes that do this without the demand for an extra 2x4.

I don't know who makes it I but grabbed the paradigm of the web. The 10-32 studs are part of a metallic bracket that goes over the back of the box. I have seen them on brandish at my local supply house.
In that location is i that is all metallic using the same principal...Arlington or Steel Metropolis makes them.

Rats! I was hoping that yous would have some secret tool or technique that would make removing an existing ceiling box (from beneath) quick and like shooting fish in a barrel! I approximate it's pretty much animal force...
I'll be looking for the steel version of that box! I like the approach! Thanks!
How can yous tell if an existing ceiling box is fan rated? I thought one requirement was the utilise of 10-32 screws to support the fan, just I couldn't detect that requirement in the code...did I miss information technology?
I don't know if it specifically mentions it in the code, but the answer lies in the weight capacity of various screws plus the abiding vibration of a fan.

I don't know if it has to say fan rated on the box or paperwork but in that location is something most the weight rating that is required. 10-32 screws are a must for sure.
