Maximize your sink's functionality! Do you have a single-bowl kitchen sink but sometimes wish you had a second basin for keeping tasks separate? Defrosting produce, and keeping beverages cold and within reach, there are many potential uses for the rinse tray! Designed to fit sinks with an 18-inch interior measurement from the front to the back of the sink, it will rest on the countertop that measures 18" front to back. The top edges measure 17 and 18 inches so that they can rest vertically or horizontally on the interior lower sink ledges. Now you can keep your product away from your meat or your cutlery separated from your big pots and pans. How you use is up to you but it will be like an extra mini-sink!
