I love this!
The Shelf Rack is made of heavy duty wire construction with a white vinyl coating that will not scratch wood shelving and easily wipes clean. The rack has wide support bars that rest on top of the shelf to create a storage basket below. Shelf rack fits on solid shelves up to 1.25in thick and at least 13.5in deep and is ideal to use on standard 14 inch kitchen cabinet shelving. The under shelf organizer helps maximize available storage space in kitchen drawers and cabinets.
