Will current ceiling junction box support fan? Not exactly sure if a fan was mounted to it prior as I recently moved into this apartment. Somewhat older of an apartment and box doesn’t directly state if fan is supported or not. Figured it was better to check first. enter image description here

  • I'd change those 2 drywall screws to something less brittle.

    Is there a joist behind the box, perchance? Oct 14, 2018 at 22:36
  • Do you already have the fan? My experience is with Hunter fans, both the very heavy old ones and the new much lighter ones. If you are installing the latter, the kit comes with two purpose designed wood screws which go into a ceiling joist or other sound wood. If you would be installing of of the old heavy fans, you would pry out the center knockout, drill a hole for a single very heavy hook. These would go through holes in the metal "pancake" box, or around the box, into the wood joist. This box itself does not support the weight of the fan. What kind of fan are you mounting?

Mount the fan to the joist or block behind the box, not the box

The two screws in the back of the box in line with the mounting tabs appear to land in a joist or cross-block in the ceiling. I would attach the fan to that using two 1/4" by 3" structural wood screws (not drywall, deck, or lag screws -- look for something with an ICC-ES or IAPMO rating, such as a FastenMaster TimberLok or Simpson Strong-Drive SDS) through the fan bracket and ceiling finish board into the structural member.

  • I recently did this for two new fan installs in my house and it worked fine. My fans came with two sets of screws, one set for going into a metal box but the other were long wood screws meant to mount to a stud like this so if your fan kit came with their kind of screw it should work.

It may, but I concur with brhans. Drywall screws are very easy to snap right off and they (at a minimum) should be replaced by even just Deck Screws, which have the shear resistance of nails.

But, as with ANY apartment, call the Landlord and get their written approval and/or have them perform the installation and ALL electrical modifications...as is likely in your contract.
