I recently had a shelf fall off of my wall (there was a good amount of weight on it: camera, lights, etc. so not surprised it fell). For context, my wall is on the outside of the home so there is concrete behind it after some empty space, and I just had it mounted with 3 screws, wall anchors and the 3 brackets included with the ikea kallax shelf I am using (mounted horizontally); this worked for a while but clearly is not the best solution. Not even sure where to start for a better alternative so am looking for ideas/tips here!
PS: located in FL, if that gives any insight.
