Review: Great design, great execution - Kind of surprised more companies don’t make a product like this. Perfect and easy solution compared to the other types of fan rated boxes. Now, I suppose I got a little lucky that the light I was replacing happened to be right next to a joist. But, even if I’d had to relocate it, this box would still prove to be an efficient time saver. Took one star away based on the knockouts. First, if you’re not familiar with this type of box, it’s not exactly self evident which portion of the tab needs to be broken off. A small edit to their instructions could fix that potential for confusion. Second, the knockouts could be designed a little better. It wasn’t incredibly difficult to remove the tabs. But it could be easier. Someone else suggested using a flathead screw driver and hammer. Which works pretty well. Beyond the above, this box is excellent. Installed in minutes, and is rock solid. My impact driver made quick work of the fasteners. If you don’t have an impact or drill/driver, it’ll take some elbow grease to get them sunk. I did have a brief hiccup, but it was my own fault. In short, when I secured it to the joist, the box ended up slightly recessed. For my application, that posed a problem. As the brackets typically mounted to a fan body are very flush to the ceiling. My solution was simple. Took another two nylon lock nuts (one on each bolt) and essentially used them as spacers. Worked perfectly. So maybe sharing that issue and solution will help someone in the future. Would definitely buy this product again!
Review: Fantastic product. - I had a ceiling fan box pull out of its place. This product is designed for installing without further damage to your ceiling. It works great! The attachment screws are a little tricky to get at directly. I used a nut driver at first then a screw driver bit to finish and tighten. The metal reinforcement makes it real sturdy. I love that there are bolts with nuts to attach your light fixture. The nuts are nylon locknuts and will never come loose. Installs easily and fast. I highly reccomment this product.
