ABSTRACT:
An apparatus is set forth wherein a plurality of spaced tubular supports include pivotally mounted angular feet at their lower terminal ends. The supports each telescopingly receive an inner support, wherein each inner support includes a "C" shaped rigid jaw for positioning about a rung of an associated ladder to provide support to the ladder. The parallel supports include spaced sleeves, wherein the sleeves include tab members, wherein each respective tab member pivotally mounts an elongate link. Each link is defined by an enclosed slot, wherein the slots overlap and include connector clamps to space the links and the supports relative to one another to provide an organization securely positioning and maintaining a ladder in a predetermined orientation.
