These magnet ceiling hooks are designed for hanging mid-weight signs, banners, fabrics, and heavier items. They feature powerful neodymium magnets that connect to any ferrous metal surface, including drop ceilings and open-beam ceilings. To prevent ceiling scratches, these hooks have a durable plastic coating and come in white or black options for blending into colored ceilings when used with Clear LoopLine. With a double center ring, they are easy to attach to signs, displays, and decor items using the patented LoopLine. For simplified usage, users can lift the magnet into position with any MagMover connected to a MagPole, making sign or display installation and removal convenient. Each magnet measures 2.25 x .8 x .6 inches (5.8 x 2.0 x 1.5 cm) and has a strong magnetic pull of up to 10 pounds (4.5 kg).
