It is excellent at holding common 18v and 20v tools. The Ryobi tools fit perfectly, as you can see in the photographs. Because the handles on the Miwaukee M18 tools don't flare out like the ones on the Ryobi tools, they stayed on reasonably well but weren't secure. If I do decide to keep any M18 tools on it, I'll just flip them over so they're upright rather than upside down, and they should be okay. Overall, this is ideal for the purpose I had in mind. It appears to be strong and should endure well. I always replace the massive plastic anchors that came with it with screw-in plastic anchors so that it can support a little bit more weight.Very nice ?I mounted it to my wall with three screws and it was ready to receive my tools.It is sturdy and holds my power tools wellI added a little work area on my shed and mounted this organizer on the wall. It’s pretty easy to secure and took me about 5 minutes. The organizer came assembled which is nice. All I had to do was secure 3 screw on the wall. There’s a wood plank on the shelf and extra storage for screw drivers on the side. I like the clean metal look. Much better than the wood organizers.
