CHADKO shelf liners and enclosures are a great addition to any wire shelf unit. Liners and enclosures are easy to install; they snap into place, no tools needed. They are made from durable, flexible 1/8" plastic (PVC) and come in six vivid colors. Liners keep small items from falling through wire shelves; enclosures give a shelving unit the look of a cabinet and hide clutter. Please specify if the liner is to be used inside an enclosure.
