These holders are not as strong as I was hoping. I also overlooked that the grip clips that hold the reels are simple curved strips that are not hinged or spring loaded. As a result, you have to bend the clamps a bit by hand to fit some of the handles, reducing the freedom of movement of the tools. I like to use paint bars for a lot of my tools, and while I was able to attach them, it definitely increased the capacity of the clips. However, they should fit on standard household brooms and mops. Pre-drilled mounting holes will not fit on 16" centers. You must use anchors. .
