Customer Questions & Answers

Can this be used with i-joists?

I was wondering whether this would work with i-joists or whether it is just designed for solid lumber joists.
Asked by: soedesh
Probably not, beacuse the grippers aren't low enough to grap a flat 2x4, which I believe is how I-joists are constructed. My review has an extensive explanation.

Can this fit within 14" space between joists?

I have only 14" between the joists. Will this fit? If not, can I cut 1" or 2" off the bar?
Asked by: Tightspot
The specifications state that this brace is 14" in length. The ends have little protrusions. Not sure about cutting the tube, however, you could chisel out a channel on either or both joists to accomodate.

Does this work with dropped ceilings?

I need to install three fans and a hanging light fixture in our basement. The basement has a dropped ceiling with approximately 8 inches between the ceiling tiles and the rafters. I want the bases of the fans and the light fixture to be snug up to the ceiling tile.
Asked by: FluffysMom
If you mean acoustic tile that sets into the thin metal framing, then this won't work. It need a structural joist or similar to grip. The acoustic tile framing isn't suitable. SOunds like you need to get up in there back to the original floor joists in the basement ceiling and connect into those.

Can this be used on a sloped ceilings?

Asked by: Shiru
Not as is. If you mounted the device so the box is at the angle of the ceiling, it is doubtful the little spikes that grip the joists will endure the weight of a ceiling fan - I suspect the fan will pull the spike loose from their seating, and the box will turn downward and the fan wouldn't be flush any longer with the slop of the ceiling.

RETRO-BRACE with 4 in. Round Ceiling Rated Pan, 1-1/2 in. Deep with 1/2 in. KO's is rated 4.3 out of 5 by 10.
Rated 5 out of 5 by from This is a high quality quality product that would work perfectly on standard joists as intended. ... This is a high quality quality product that would work perfectly on standard joists as intended. However, in my case, I was working with a ceiling that was hung below the joists on 2x4s laying flat. Thus they presented a 1 1/2" surface for the brace to grab and the spikes to dig into. However, the spikes are about 2 1/2" from the surface of the gypboard when properly placed, so the spikes were above my flat laying 2x4s and couldn't grip the 2x4. This is not a criticism but a suggestion: also place spikes at the foot of each leg assembly to that the unit can grip something less than a upright joist. BTW, I was willing to provide this feedback directly to the manufacturer, Hubbell - Raco, but customer contact info was nowhere to be found on website. (Footnote: I was not installing a ceiling fan, just a lightweight pendant light, so the load-bearing capability of the flat 2x4 wasn't an issue.)

Rated 1 out of 5 by from Disappointment Easy to install. Bar is very strong (to include the end "feet" grips on joists. HOWEVER...there is NO WAY to prevent the electric box bracket from rotating around the bar. Of course, once you screw the electric box to the bracket, the box will prevent anything close to a full rotation. However, the box/bracket assembly is still free to "wobble" around the bar. So, of course, once you install and turn on the fan, it wobbles. It's not going to fall down, but it's still super-annoying. I tried several tricks to prevent this, but nothing worked. There really ought to be some sort of set screw, better bar geometry other method, or other method to prevent this. Bottom-line: I recommend buying some other brace.

Rated 5 out of 5 by from Reasonably priced and easy to install I bought the RACO old work box to replace a ceiling light box that was being used to hold a ceiling fan. The box was sagging and causing a real wobble in the fan. It took longer to remove the old light box than it did to install the RACO product. Installation went very quicly and when done, the ceiling fan box was about 1/16th of an inch above the bottom of the ceiling. The ceiling fan was reinstalled and it worked great with no wobble.

Rated 5 out of 5 by from Easiest electrical box installation ever. Although this brace is ideal for retro fitting from below, I had access to my attic and was able to install this with no problems whatsoever. The brace telescopes via an internal screw and extended to the required length to fit tightly between my 24" on center trusses. See photo. The "legs" at either end of the rod provide precise adjustment and stability. My ceiling fan was rock solid after installing from this Retro-Brace After installation, the box was flush with the bottom of the sheetrock. The next size (depth) is twice the price so use this one unless you really need more depth for wires and nuts.

Rated 2 out of 5 by from Depends on your situation The whole purpose of this bracket, is so you don't have to go up into the attic. If you have no insulation between rafters this bracket will probably work great or the rolled in pink insulation you might be able to push the pink stuff up and put this bracket in. I have the 24" of the blown in stuff, I ended up with a laundry basket of insulation on the floor which fell threw the 4" outlet box hole, before I gave up and went up into the attic.The bracket is very strong, probably strong enough to hang on, but there is no way to tighten up the outlet box, it will still spin around no matter what you do causing the fan to wobble.

Rated 5 out of 5 by from A lifesaver for a retrofit! I needed to relocate a light fixture in order to center it up properly on a new kitchen table. Nothing worse than all the trouble to move a box 9 inches! I needed an innovative product that would allow me to hang a heavy light fixture and not require any additional holes in the drywall for installation. This baby was the ticket! It's sturdy and easy to install (watch the manufacturer's YouTube video). It's strong and well constructed but I did notice the way that the saddle tends to wobble a little on the bar even after installation. It wasn't a big deal in my case for a light but same say this can lead to fan wobble. A simple addition of a set screw would be a simple deign fix for this. In the end it was a lifesaver!

Rated 5 out of 5 by from Why can't all products be this good? This box is nothing sexy or outlandish. It's just an electrical ceiling box, but for doing old-work projects, this is indispensable. I bought 4 for a kitchen/living room remodel I am doing. The bars are solid, parts well machined and tapped - all needed parts are included. A little planning allowed me to get these shipped to store for about 3/4 price of the ones stocked at the store. I didn't install any fans, but these things are pretty beefy - I'd have no trouble putting a 50lb fan on one of these boxes.

Rated 5 out of 5 by from Great Product. Does the job! This absolutely did the job. I'm not the most handy person, so I was a bit concerned but once I put this into the ceiling, I was easily able to expand between the ceiling joists without an issue. It's very sturdy too so no worries there.
