Perfect for metal school chairs and institutional style metal desks, the slip-over protector with thick felt pad has a low profile and fits securely around each foot to protect the floor from scuffs and scratches. Better than tennis balls on the feet of classroom chairs, the slim design of the slip over floor saver won't get in the way of students moving about the room, in and out of chairs and the fit stays securely in place. Use the metal installation tool to stretch the heavy-duty pliable sleeve and fit the slip-over felt bottom glide onto each chair or table leg. Buy Slip Over Floor Savers in small or bulk quantities of 4, 48, 100, or 1000. Install tool is included with larger packs only.
