I work in the corporate offices of a large retail company. These are the same grid panels that we use in our retail stores to display merchandise. These grids are very versatile. 3 inch grids are a standard size with hooks, hangers, brackets for shelving, baskets, etc. readily available to customize the grid to meet your need. For my application in a small closet where I hung the panels horizontal, I needed to trim a little off the length of one using a SawZall with a fine tooth blade designed to cut metal, and a couple of the tack welds on the end of the grid failed. A dab of SuperGlue Gel repaired it, but I knocked a star off the rating for the bad welds. For the cost, as compared to other wall systems, these are a good value. I'll be buying more of these grids to install in my garage and backyard shed.
