Madison Electric Products MSBFAN Fan Support 50/ lb, Maximum with Depth Adjustable

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!

I 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.

old 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.

Muy buen aditamento, en México no es posible conseguirlo ni en las grandes tiendas ferreteras, pero el incluirlo dio una fijación perfecta a mis ventiladores (3).
