  • Adjustable height tool bin system
    Patent number: 6098748
    Abstract: An adjustable height tool bin system for self-supportive ladders includes an adjustable length strap allowing positioning of the tool bin at any height between the top and bottom of the ladder. Thus, the position of the present invention is independent of the ladder rungs and ladder platforms, allowing more freedom in placement of the tool bin system. The system also includes an attachable roll towel rack, a winding spool, a utility tray, a hook, a tool rack, and bin dividers each of which may be attached to the tool bin or the strap.
