Magnetic vertical sign holders feature gripper fins that hold onto your signs and papers up to 1/10" thick, extremely tight. This firm grip, combined with the strong magnet, make these sign holders a durable and reliable solution for inventory labeling, shelf signs and so much more. For larger signs, multiple holders can be used for added strength. You can buy magnetic vertical sign holders online in two styles: a standard style that will hold your sign parallel to the wall, or a hinged style that can be pressed forward and back 180° and return back to its original position when bumped, making it ideal for high traffic areas. All of these magnetic sign holders are sold in packs of 10 pieces, and are easily removed and changed out for temporary displays.
