Modify existing flat shelves to exhibit the latest issues of magazines and newspapers face-out, without purchasing additional periodical shelving. Covers define space on shelving and clear 1/16" thick plastic acrylic keeps them in full view. Up to 4 magazine displays or newspaper displays will fit on a 36"W shelf. The 3M™ removable adhesive strip adheres to any surface and won’t mar shelving. Title signage can be applied to back surface of adapters. Easy access to back issues behind each adapter.
