Universal® Magnetic Bookends provide a firm, secure, and reliable holder for books and files. The strong magnets in the base prevent bookends from slipping. Keep items secure, even when holding large and heavy books and files. On non-metal surfaces, it's recommended to flip the base inward. Great for organizing books on files on top of file cabinets, desks, tables, and bookcases. Material(s): Metal; Color(s): Black; Finish: Standard; Height: 7".
