To buy: $20; amazon.com. The expandable rack ranges from 16 to 32.5 inches wide, and it’s detachable, so you can use the shelves separately as well. It has a non-slip and rust-resistant coating to keep your items in place, along with foot grips to stabilize the shelf and prevent it from scratching your cabinets. Plus, it comes in five colors to match the decor in your home. “I got this rack to organize canned goods in an off-size cabinet,” the reviewer said. “The shelf is adjustable to fit the odd width of the space, and it retains its strength to hold up a dozen and a half or so cans and packages, while allowing storage below for more. This was a very affordable fix for storage that makes cooking and shopping easier, because I can see in an instant what is on hand and what is needed.” Another shopper said, “Our freezer didn’t come with a shelf, and it was a pain to move stuff around because they were stacked so high and tended to fall off. With this shelf, we gain extra stable space at the bottom. At the bottom, frozen food can be slid in or out with ease. The topper space is more stable too, because they don’t pile up that much compared to before. Nice stuff for life hacks.”
