      Q:So my wood Joist are about 16in apart. My box is going to be close to one of the Joists, so the box is going to be almost at the edge of the adjustable bracket. Will that affect the weight it can handle?

          Power off- test voltage. Make a hole- Dry fit bracket- Insert into your fan fixture opening. Remove box and center bracket, tighten by turning it. Once secured, pull your wires and use the plastic grommet and feed wires then install the box to the bracket bar. Mount fan and test.

          Reliable
          Feels very sturdy in ceiling once installed. Only sore point is it’s a bit difficult and requires trial and error to get the bar positioned perfectly over the center of the hole, so the box mates up to the bracket correctly. Also appeared to be 1x extra threaded hole to fix the box to bracket that wasn’t noticeable when taking the bracket apart out of the box

            New kitchen lights.
            Used this to replace 2 recessed lights with hanging multi light fixture. Way over strength for the application since this is designed for heavier ceiling fans but installation was a breeze. Minor downside was the crosspiece bolts are bigger than the slots for a standard light fixture but was able to drive them through anyway. Could have slightly drilled the crosspiece instead. Got the shallower, and less expensive, junction box version since I didn't need the depth.

            Fixture mounting holes rotated 40° from brace
            I installed three of these support boxes to use with pendant lights. Before installing them, I had given no thought to the fact that the two mounting holes for attaching the fixtures are rotated about 40° from the direction of the brace. For lighting fixtures that are intended to have an orientation parallel to or perpendicular to the ceiling joists, this presents a problem because the fixture canopies will not align with the joists. Made in China.

              Just right!
              I was concerned that this brace would not work in the peak of a sloped ceiling because all of the videos I viewed showed only flat or sloped applications. After locating the joists, I made a hole in the crook of the peak, maneuvered the brace/bar into the hole and straddled it between them, tightened it and hung the box for a secure fit. Excellent!

              Easy Installation and Sturdy
              I bought this product at the Woodbury store on July 2nd. The brace is well designed and very sturdy. Installation was easy. Make sure both ends of the brace are sitting upright on the two feet (see picture) and it will be level and the proper depth for the box. The bracket fits fairly snug on the bar and the use of nuts makes it easy to attach the box to the bracket (much easier than trying to start screws into a bracket). Don't forget to install the additional two screws upward into the bracket. After installing the brace, neither the brace or box would move. After installing the fan and light there was zero wobble, even with the fan on the highest setting. I am very happy with this product and believe it is an excellent value.

                Great ceiling brace!
                Bought this over the other brands because I had great success on CE products. The brace is very strong once is installed properly.

                    I replaced four recessed can fittings in a cathedral-type ceiling with these fan braces. As the can wiring had been butchered in a previous modification to hang pendant lights, a regular can to pendant conversion kit was not an option. Going this route allowed me to do a clean job of the wiring and restore the ground connections. Removing the airtight cans was a major hassle, as they were solidly-made USA-manufactured, rather than a modern imported type. I also found very poor insulation around the cans and usually nothing between the can and the roof sheathing, leading to the cans becoming too hot to touch when the afternoon sun reached the roof. One of the installations required the use of the version of this brace with a slightly larger box because of the number of cables it had to handle. Installation through the old larger can hole was very easy. A paper template helped to create a drywall patch to adapt the can hole to this box's 4" diameter. Overall, actual installation of this box was a breeze.
