2 Pcs Folding Shelf Brackets Heavy Duty Collapsible Wall Mounted Table Bracket

These folding shelf brackets use a unique design to provide a very strong platform. The simple, press lever design allows the shelf to be folded and dropped against the wall when not in use. The brackets can be mounted out of sight behind the shelf, and you can even decorate or put graphics on any shelf top used so that when folded flat it doubles as wall art.
