Wider cabinets need a wider tray, and this 17 by 21 by 2.5 inch slide out fills a base cabinet with an internal opening of 19.5 by 22 by 7 inches, roughly a 21 inch cabinet in most kitchens. Pulling the shelf forward exposes the entire depth at once, which turns a cabinet that hides its contents into one that shows them. Chrome-plated steel handles the moisture and cleaning product spills that occur under a sink, and the wire deck drains rather than trapping liquid. Rated capacity is 28.6 lbs, enough for stacked pots, small appliances, bulk canned goods or a pantry load of jars. The organizer weighs 6.4 lbs and installs into the cabinet floor with the supplied hardware, adding a drawer function to fixed shelving without replacing the cabinet. The tray measures 17 by 21 by 2.5 inches on a single ply chrome-plated deck. Slides mount to the cabinet floor rather than the side walls.
