The Craftsman® shelf bracket mounts to VersaTrack rail to create a flexible and convenient storage system. Its Hooktite latching system secures the hook to the rail so that the hook will stay attached to the wall when you remove your stored item. The two brackets hold one shelf, three brackets and can hold two shelves. It will hold the shelf above the rail, allowing other hooks to be mounted below. Can be used with the VersaTrack wire shelf or with any 10'' deep wood or laminate shelf. Heavy-duty reinforced steel construction. The holes along the bracket can be used to hang small tools and supplies. Two brackets support up to 50 lb (each bracket sold separately). This product is backed with a 1-year limited warranty.
