If you have run out of room in your cabinets, this chrome expanding shelf will give you the extra space you need. Since it slides to enlarge, you can custom fit it to your cabinets and their contents. You may want to slide it completely open, for maximum extra storage, or only partially open, to accommodate items which need more height. The chrome expanding shelf is 5.71x8.66x20.28 inches, so it is tall enough to allow you to place it over many items which are already in your cabinets, and turn the wasted space above them into useful storage.
