ABSTRACT:
The instant invention is directed to increasing the safety of ladders and includes an accessory holder for the top of ladders forming a tray which expands in size allowing placement of working materials in the tray. The tray collapses into a size assimilating a conventional ladder top for compact storage. The tray can be raised to various heights and allows the operator to remove the tray in its entirety to carry items to the ladder providing for convenience and safety. An alternative embodiment provides for the use of solid portions in place of a tray allowing smaller ladders such as to be used as saw horses yet provide a means for forming a smaller tray for securement of miscellaneous working materials. The improved ladder employs handles that couple to each side limb of the ladder allowing an operator to grasp the handles while climbing. An electrical socket mounted in a limb provides for a prewired extension along the length of the limb providing an electrical connection near the top portion of the ladder. Biased wheels allow the ladder to be moved without lifting.
