Richards Acrylic Closet Shelf Divider and Separator 6 Pack- Great for Storage and Organization in Bedroom, Bathroom, Kitchen and Office Shelves, Clear (9875300-3)

They fit over even very large shelves, but tend to loosen up and lean or slide with heavy stacks of clothes, etc. They were much cheaper than some of the other dividers and definitely more versatile and flexible, but I wish they would tighten and stay tightened!

We have high shelves, and the stacks of sweaters would always tip over. Problem solved

easy to install

This product is better than others I’ve tried. It will fit on any size shelf as is it easily adjustable. Plastic will snap others if stretched too far.

These do make my closet look more organized, however 2 out of the six I purchased were broken. Luckily my husband is handy and should be able to fix them so I can use them.

Work exactly as described, super easy to install, and very sturdy. For any wondering as I was, you can absolutely use these for bookshelves. I was unsure if these would work when I bought them, questions like would they be sturdy and stable enough to hold up under the weight of books? But I took the chance and they're perfect.I needed to add dividers to a very long bookshelf in my young daughter's room because everytime she removed a few books they would lean and fall over and make it impossible for her to put them back in. By getting these dividers we not only could sort her books into easy to find sections, but by having them in smaller sections they no longer fall over and its easy for her to put them away.They lock into place and don't move once locked down. Even though they aren't as wide as our shelf is deep, they still get the job done. Just be aware if you have an extra wide shelf like we do you'll have to make sure your books are between the dividers which may leave a gap behind depending on the overall size of the book(s).Overall great item and I'm actually looking for reasons for how I might use them in other areas of my home. Would buy more if I find additional need for them.

You’ll be hard pressed to even find a shelf organizer that is adjustable and fits shelves larger than 1”. This works perfectly.

Pro: Arrived quickly and they're fairly sturdy. They worked as shown in photos and installed over my extra thick shelf edge. Con: It took me a minute to figure out how to attach the first one but after I did the rest were easy. It doesn't take much to make them lean at bit if clothing is tight on one side. I think the attachment "clip" is unsightly. I solved it by pulling my clothing out a little to cover them.
