This is the shelf that attaches to the side of a utility sink and folds away when not in use. The sideboard provides 351" sq. of workspace and its grooved surface channels water towards the sink, making it an ideal place to water plants or clean paint brushes. The built-in hinge adjusts the sideboard to three different heights and allows it to fold flush against the sink for unobtrusive storage. Made from waterproof, stain-resistant polypropylene, the sideboard supports up to 25 lbs. and has seven slots around its perimeter that accommodate clothes hangers or tools. The unit simply slides onto the front or side of a sink without requiring hardware installation. 19 1/2" L x 18" W. (6 lbs.)
