Customer Questions & Answers

Is there one of these for a 20 pound fan?

My hunter 52 inch fan with light is 20 # in the box.
Asked by: PatB
This model should work. I hung a 52" Hampton Bay fan with light kit and have zero wobble.

Can this be used in an outdoor (covered deck roof) application?

Asked by: JohnA
This answer is directly from the manufacturer: There is not an actual damp location “rating”, as there is for a wet location. For an item to be used in such a (wet) location, it is up to the electrician or inspector to make sure water will not pool on or around the box. With that said, the 937 should be allowable to use in the application you have described. (outdoor deck with a covered roof).

Would you use this to hang pendant lights?

Asked by: KM1129
Yes. This might be overkill but it will definitely work. I hung a 40 lb ceiling fan using it and I have zero wobble.

Box for heavy chandelier

What kind of box do you manufacture for a chandelier waiting 90 pounds?
Asked by: LG
I'm not sure I would trust this for something that heavy. The brace is actually resting on the drywall while being secured to the studs on the side. While you will get some friction and support by being scewed in to the studs, you still will get some force on the drywall. Me personally, 90 lbs in too heavy for this brace and you need something that is secured to the studs.

RETRO-BRACE with 4 in. Round Ceiling Rated Pan, 2-1/8 in. Deep with 1/2 in. KO's is rated 4.3 out of 5 by 10.

Bought two of these and in both cases I wasn't able to get the box to strap securely to the bar. I was using a ratchet wrench with extender bit and the nuts would strip before the box was tight. Ended up buying a version made by a different brand and was able to install it in just a couple minutes. Much better design for box attachment and uses a total of 4 screws instead of 2 to make sure it doesn't budge.

The ceiling joist in my old home are less than14 inches wide so this product proved very easy to cut down in size. First I hack sawed about three inches off one end where the threads are and careful not to cut into the threads. I then cut a similar amount off the threaded screw. Once shortened I simply used a punch to bang out the threaded insert and carefully tapped it back into the shortened tube and screwed the threaded expanded in. Now the brace was very easy to install in the ceiling. Connecting the box to the brace bar was a bit more challenging but after trial and error I got the box attached. This deeper box was perfect in the original hole through the plaster from a previous light fixture box that was not fan rated. Once this brace was screwed tight to the joist it will definitely support my new Hunter ceiling fan and I'll feel confident sleeping underneath a spinning fan. My thanks to another review that gave me the idea to cut this brace down since nobody seems to make an old work brace for closer joist.

Rated 5 out of 5 by from I'm a DIYer and never installed a brace before. I was able to install it in about an hour. The mo... I'm a DIYer and never installed a brace before. I was able to install it in about an hour. The most difficult thing about installing this brace was removing the old one. There's very little info on the web as to how to remove an old brace attached with nails. I needed to remove the old brace because it wouldn't hold a new fan I was installing on an angled ceiling without access from the attic. My advice is to do whatever it takes and get that old brace out! I used metal cutters (tin snips), a small pry bar and long flat bladed screwdriver. I have long skinny arms, so it was fairly easy to get my arms inside the four-inch wide hole in the ceiling and reach back to the joists. The 'cotton candy' insulation irritated my arms and throat. I followed the instructions and it went okay. I'm glad I bought the 2" box because I had a bunch of wires to stuff inside it. I would caution using the one (why not two?) bushing that came in the box. This bushing has sharp edges and a small opening to pull the wire through. The edge was removing the insulation off the 3 wires I attempted to pull through it, so I did NOT use it! There are three knockouts but you can only use two of them. The brace solidly attached to the joists and the fan has no wobble. This is a good product and recommend it.

Rated 4 out of 5 by from Excellent product, but installation was not as easy as I thought I wanted to install a ceiling fan in the dining room, but upon removal of the old light fixture I found there was just a plastic electrical box instead of the metal boxes I've hung ceiling fans from in the past. I knew over time it would certainly fail if I attached a 30-lb. spinning fan to it, but since the fixture was located in a condo with no attic, I was at a loss as to how to reinforce the box. So I did research and found that there was a "simple" solution to my problem -- a ceiling fan brace. If you watch the videos online detailing how to install this, it appears to be something that could be put in in less than 15 minutes, and I think in most circumstances, that is true. But I was the exception to that, and you might be too, so read on. Removing the old plastic box was pretty straightforward -- after shutting off the power and detangling the wires, I started snapping the box apart with pliers until I found where it was mounted -- 2 nails going directly into a joist. With a bare hacksaw blade I was able to sever both nails and the plastic wings they were held to in about 10 minutes. The box came out quite simply after I enlarged the hole in the drywall slightly by scraping the edges with a utility knife. Now the fun began. I fed the brace up into the hole and tried rotating it to be perpendicular to the joist, but it just didn't seem to fit. After some measuring, I discovered that my joists were about 12-13" apart -- and this brace at shortest extension is about 14". It's designed for standard 16" or 24" joist spacing. I was livid, naturally, but after cooling down and some repentance, I remembered reading a review on another website where a fellow had faced the same problem and had solved it by trimming a few inches off the tube and the screw with a hacksaw. 30 minutes later I had disassembled the brace (quite simple, mine just pulled apart with a bit of muscle) and cut 3" off the end of the tube and a similar amount off the end of the screw with my hacksaw. I slid it back together and gave it a few whacks with a hammer (using a bit of wood to protect the teeth on the end of the screw) to secure it and I fed it up into the hole -- it fit great! There is a competitor to this brace made by Westinghouse. It's very nice but it cannot be customized like this -- at least not as easily as the Raco version. I took the Raco apart while working at a rental property without the help of my workshop or all my tools. I think the Westinghouse is just not designed to be taken apart or you would need a vise and some tools to pry it apart. So if you have joists less than 16", the Raco is the way to go. Now, after I put the brace into the hole, it was a struggle to get it aligned properly. I had it all tightened at one point and realized the legs were upside-down on the far end. It takes some fiddling to get it right. And as for tightening it, in the videos they show you easily reaching into the hole and twisting it without effort. Unless you have tiny hands, you will need to use channel locks to twist it. Once it was secure -- and it is VERY secure, I feel I could have hung from it without problem but did not test this theory -- I slid the bracket on and attempted to attach the new box. Aha! The hole is too small. So I enlarged the hole, and tried again. What? The screws don't line up? Why not? Well, unlike in the videos, the hole in the drywall was right up against a joist, not dead-center between the joists. So, the brace's feet get in the way of aligning the new box to the screws. Solution? You have to enlarge the hole even more to get the box to line-up with the bracket. After 5 more minutes, that was done and I finally had the box mounted onto the brace! Thank goodness the ceiling fan had such a large trim cover to it to cover the enlarged opening. Now, last step: The box comes with one plastic bushing to feed your wires through into the box to protect them from the sharp metal edges. Notice I said ONE bushing -- wonderful except I had TWO cables coming into the box, requiring a second bushing! Incredibly frustrating to have to stop everything to source a 50-cent bushing to finish the install. So this is my only complaint about an otherwise excellent product -- it is not unusual at all for a ceiling box to have multiple cables running into it, so why does Raco only provide ONE BUSHING??? I mean, how much more would it cost Raco to put 2 more into the box? 10 cents? Raco -- PUT EXTRA BUSHINGS INTO THE BOX!!!! Please! So, once I had the new bushing and the wires connected, I had a super-sturdy base to mount the fan to. With tenants and associated liability issues, I cannot tell you what a comfort it is to me. And this brace cost me less than $13. If they put in some more bushings, it would be perfect.

Rated 5 out of 5 by from Great product easy to install Couple notes: You may wish to take the box place it over the original and draw around it, for it is probably a little larger, this way you can trim the hole with a box knife - If the original is nailed to side of truss, best to move hole 1" away from it and plan on mudding around the open side - tape a thin piece of cardboard to the top side, trimmed to the box helps to make this easier also.

Rated 5 out of 5 by from Great buy - the ONLY box to use for old work I shopped around and did research before buying this product. It is by far the best. There is a YouTube video of the installation to help. I put this in to hold a ceiling fan and it worked perfect. Super easy to install, just keep the feet on facing the ground. The hole is just large enough that I was able to get my entire hand up in the ceiling to check the side 2X6's that it used to brace. Do not settle for imposters, buy only the RACO brand.

Rated 5 out of 5 by from Great box, YMMV Full disclosure: I had complete access to the ceiling from above. That being said, this box's strain relief is not enough to hold two old style 12/3 wires. The wiring I was using was part of an old four circuit fuse box since upgraded to a 200 amp circuit breaker. Unfortunately I haven't had a chance to rewire the house yet. Anyway, this problem was easy enough to fix as I just removed two of the knockouts and used some regular screw in strain reliefs that I had. It was snug inside the box and the two tension screws on each strain relief had to be facing outward in order to screw the bar mount to the electrical box properly, but eventually I got it to work. Now if i hadn't had access to the attic there is no way I could have done this, so make sure you have the access needed if you're going to be using this as a junction box as well as a ceiling fan mount. Otherwise the mount is terrific; that fan isn't going anywhere.
