The Progressive Green Collapsible Over-The-Sink Colander is a must have for any kitchen with limited storage space. Its unique design allows it to remain rigid enough to stand on its own when straining yet makes it simple to collapse it down to 1/3 of its original size for easy, convenient storage in a cabinet or on a shelf. Its adjustable arms extend to 24", making it possible to use with a variety of sink sizes, and its specially designed pattern of holes allow water to drain quickly and efficiently. It also boasts non-skid tabs on its handles to prevent slippage during use. Plus, clean up is a breeze, as it is dishwasher safe in fully open or collapsed position. Made of plastic. Dimensions: 15.50" x 10.50" x 4.75". Capacity: 6 Quarts.
