This spice rack was too thick for my actual cupboard. The rails kept it from closing within the corner cabinet where I wanted it. Not sure if I misread something? Or did it wrong? I'm not sure how they got it to be on the inside of the door and could still close it. Anyway...I ended up putting it on the outside of the cabinet because it happened to fit there and the product itself is AWESOME. I love being able to adjust the shelf height and it looks really nice. It's also stable and high quality.
