They look sturdy but are bigger than I expected. I was trying to use them for the small Suncast Vertical Shed (approx 3ft W x 2ft Dx 6ft H). After seeing them in person, I realized they would take up too much real estate in the shed. The shelves (purchased separately) are more important to me than these baskets, so I will be returning them. However, I wouldn’t hesitate to buy them again if I  had a bigger shed. They would be great for a shed that has really wide doors or for deeper sheds (at least 2ft 8in deep).
