These Invisible Disc Adhesive Plate Hangers hold china, porcelain, crafts, large trays and platters, and home decor of many different sizes and shapes. Each plate hanger holds up to 7 pounds. Use 2 or more disc hangers to hold heavier pottery, trays, and decor. These 5.5" Disc Hangers work great to hang heavy trays and platters, large glass and mirrors, chargers, and some heavy metal objects. Their size allows you to trim them to fit odd shaped items and avoid rims and edges. (Trimming plate hangers can reduce the amount of weight they support.) These disc hangers come packaged with The Flatirons Disc Co directions and packaging on heavy card stock.
