These are great. Very sturdy. I use them to display a rifle collection. The displays vary from 6 to 13 pounds each with 3 to 4 rifles per grid. There is no sag or weight related issues. Far better than attempting to mount individual hooks. Additionally, I can change the displays easily as I add or remove an item. Four stars because the shipping box was not sturdy enough for the grid weight. Cardboard broken in a number of places and grid was exposed. Some chips in paint but a magic marked will touch up.
