Patent number: 6061909Abstract: A peg board panel for supporting a bracket or other generally available hanging element. The panel is comprised of a fabricated metal panel having a front surface, a side surface, a rear surface, and an array of holes extending through the panel. The holes are first punched and then extrusion formed to create an upstanding annular flange extending away from the rear surface of the panel by a predetermined distance or extent. A bracket having a hook is supported by the panel by extending the hook through the hole. The annular flange strengthens the panel and provides a rigid support for the bracket. The hook also has an extent which is equivalent to the predetermined extent of the flange so that no play exists between the bracket and the panel, eliminating brackets that sag or pull out of the panel. The panel diametrical hole sizes and spacing can be varied along the panel.Type: GrantFiled: July 31, 1997Date of Patent: May 16, 2000Assignee: Ready Metal Manufacturing Co.Inventor: Leonard Laskowski
