I thought I was going to have to return these at first because (as you can see from my pics,) these shelves are a tad wider than 15" at the top. My cabinets have a frame around the front and I could not just slide these on the shelf like I thought I could. After thinking a bit, I realized that if I angled them in and then removed all the "stuff" from the shelves, I could tip the shelves down, almost vertical and then slide on the basket and then return it to horizontal position without any issues. As you can see I was determined to get these to work. They are perfect! They aren't going anywhere either! So, if any of this made sense, please note that the shelf at it's widest point (where the hooks slide over the shelf) is about 16.5" wide. If you have that space, you'll be fine. I also included a pic of how much space between the bottoms of the basket and the shelf above it. I was looking for something to organize our ramen noodles so they wouldn't be thrown all over the place. As you can see these baskets work perfectly! So happy that these worked out! Definitely recommend!These came yesterday. Exactly what I want except they don’t fit any cabinet in my house! I have to send them back. If you have skinny shelves, these will probably work for you...darn it! ?These baskets are high and heavy duty. Was going to buy the pull out ones, but it was out of stock. I'm glad it was. These are just what I needed.Man, I love these baskets. They are all you want them to be. The only improvement might be a non stick gripper to keep from sliding. But that only happens when I cause it.It makes the most of unused space for sure. Will be buying another setNice to have extra shelveWe have a tile counter we love and I was sick of seeing fruits, vegetables, etc. pile up on it (stuff we don’t keep in the fridge, spices too), so now we use those under the cabinets and our counters are free. Looks better and we have more counter space. (We might need to adjust the hinges on the cabinet doors so they close, because the flat rods that hold on top, inside the cabinet do keep the doors from completely closing — but well worth it)This mesh shelf was just the right size and depth for my small closet. I have been waiting to have a shelf cut to size for my closet for some extra small items, but the shelf never got cut, so I ordered this mesh shelf and it was perfect. It is sturdy and deep enough to match the shelf I added it to and high enough to accommodate all my items.One of the baskets came bent and had to fuss with it. That’s why only 4 stars.
