I was so excited to receive and install the Rev-A-Shelf. After walking around my kitchen trashcan for almost eight years, it's a real delight that it is now hidden in my cabinet. I installed it myself (60+ year old female) without a hitch. I did add screws - it came with four - but it would have been just as secure and anchored with the four that were provided. My opening was only about 11.5" as I recall.
