The slots are too small for ordinary garden tool handles. The slots are about an inch wide at best, but most of my gardening tools are 1 to 1.25 inches in diameter. I could slide my medium-duty blades into the slots with more force, but my heavy-duty blades would never fit. (In the photos, the medium-duty example is a wooden handle, while the heavy-duty one is orange metal.) I was wondering if I missed something in the reviews, but looks like I'm the first to review this article Tried garden tools. This might work well in a broom closet but I've already arranged it so I'm returning this item. I'm just glad I checked before I put holes in my walls.
