Change the look and feel of your storage area with the HSS Shelf Liners for 18" x 48" Shelves. This product is ideal for racks and more where small or thin items are stored. The shelf covering for wire shelves will provide a smoother surface for your rack and prevent smaller items from falling through. They come in a 5-pack. Each one is made from opaque polypropylene plastic that is flexible and simple to clean by wiping with a damp cloth. They are designed for easy installation and care. The opaque plastic shelf liner gives you the chance to store more objects that might otherwise fall through the wire shelf.
