11" deep by 10 3/4" high by 4 1/8" wide. There are rubber tips on the bottom to keep it steady while pulling out the individual racks. Each rack pulls out individually and swivels to the front for access. I hope this helps.
10 3/4" high by 11" deep by 4 1/8" wide. Each rack slides out individually and swivels to the front for access. There are rubber tips on the bottom so it does not slide around when you pull on the rack. The first picture is with one rack pulled out slightly, the other picture with it swiveled around to the front. I hope this helps.
No installation required. There are rubber tips on the bottom to keep it in place. If you like, there is a rubber type shelf liner that works well also. I have that under my pots to prevent scratching. Hope this helps.
