- Reviewed in Canada on October 7, 2024Verified PurchaseI wanted to install a ceiling fan but the original box was not rated for it. After removing the original one, which took some coaxing, I installed the new one with minimal fuss and without having to make any additional cuts on the drywall. Installing the fan afterwards was a breeze, and it stays firm and secure. Excellent product, solid build (thick plastic supported by a metal structure) and very easy to install - you just need to drive the 3 screws that come with it onto the side of the joist. The screws even come positioned so that you can screw them at an angle that allows the use of any power screwdriver.

- Reviewed in Canada on October 18, 2020Verified PurchaseThis product is awesome .love it , highly recommend it., I'm no expert so it took me a couple of try to get it right..tips for a novice .u would need a powerful gun like a dewalt etc to drive screw in .I had to replace the shinny screw,white long square head Deck screw, as the bit eat out the head so that can be a serious problem to get in an out when u have to .(as I said I'm no expert).
Then u needed to knock out the side of the top corner ,which I didn't know that's was the purpose it was made that way .to pass the wires in the box .I put it at the side the first time an the wire was pinching and shorting out.hopefuly this can help someone who is not too bright like me . cheers
- Reviewed in Canada on March 26, 2023Verified Purchasemy electrician felt the spreader style fan boxes would not suit our style of joist so we were happy to find this beefy and easy to retro fit box.
- Reviewed in Canada on November 17, 2021Verified Purchaseold fan mount cracked (plastic), this one fits perfectly (4"), the 3 long screws pin the mount to the 2x4 very tightly and the back metal L bracket is the key. Fan mounted easily and felt very sturdy.
- Reviewed in Canada on August 16, 2021Verified PurchaseSo what I like about this product is that it's easy to install. The fact that the 3x hex screws are driven at an angle upwards make this an incredibly easy installation. The other fan boxes need to be installed with screws parallel to the ceiling, so it makes it incredible hard to drive in screws in a 4 inch opening.
The box does move a bit when you drive in the screws, so just make sure that the box is inside the ceiling a bit if you can't get it perfectly level with the ceiling. As long as the box isnt sticking out past the ceiling, it'll be a clean install for basically any ceiling fan.
The bad: what the heck kind of design is this with the "knockouts"? I put it in quotations, because it's literally a small triangle opening that you need to bust open with a screwdriver. It doesnt do a good job holding the wire in the box, and it's very very small.
If it wasnt for the stupid "knockout" design, this would easily be a 5 out of 5 product, but as it is, I can only rate this 3 stars.

5.0 out of 5 stars Great product, great invention
Verified PurchaseGreat invention, great product. Removed old ceiling light to install a new LED light with ceiling fan. Upon inspecting existing J-box, it was not sturdy and had a lot of 'play' (movement). Upon removing the existing J-box, see that it is not screwed into stud, but rather a metal canopy. Looking thru the hole, I can see a beam (stud) about 2 inches away. I did not want to crawl into the attic to extend or create a stud.
Then I found this product which has 1 flat side that sits flush against the existing stud. That flat side and backside of the J-box is reinforced with a solid metal plate. This product saved me the hassle of going into the attic.
The worst part and biggest repair job was enlarging the existing hole by 2 inches to reach that stud.
Great product, great invention.

4.0 out of 5 stars Don't let it ruin your 8mm socket!
Verified PurchaseWas a bit hard to install because the screws have a hard time going into the stud and the angle is quite difficult. The screws and bolts are made of very hard metal that is resistant to stripping. I ended up using a 8mm hex socket to try and tighten the screws and it ruined my hex socket. Had to borrow a friend's 8mm and it started stripping that socket too!! Not happy about that, but overall it works well, very sturdy plastic that is holding up my ceiling fan.
