New and unused.  These brackets are designed to mount small satellite speakers with a single-bolt, two-hole (2" - 2.75" spacing), or keyhole mounting systems. Each bracket can support a speaker weighing up to about 10 lbs. Each bracket can be tilted and swiveled, so you can point each speaker to the proper angle for the optimum audio experience.  The brackets can be mounted to wooden stud or brick/concrete/hollow-block walls and includes the hardware necessary for either type of mounting option.
