About Brackets -- for "No See Ums"™ invisible quilt hanging systems.
Each of the types of brackets have a small tab on which the telescoping bars rest. The tab pushes a bit of sleeve fabric into the slot which runs the length of the bar.
Hook-brackets are used with pipe and drape displays to hold tall and wide quilts. These are the quilts you would like to hang right at the top, just skimming a bit under the top pipe. They are a one-piece construction and fit into the end of a hanging tool. Quilts are raised with two people standing behind the quilt and lifting together.
