ABSTRACT:
A new ladder stabilizing device for mounting to a rung of a ladder for helping keep a ladder resting against a pole stable. The inventive device includes a U-shaped stabilizing member that includes a pair of spaced apart elongate stabilizing arms. A proximal end of each stabilizing arm has a spaced apart upper and lower proximal end region which forms a rung slot between them that receives a rung of a ladder of the type which includes a pair of rails and a plurality of spaced apart rungs extending between the rails. The upper proximal end regions of the stabilizing arms are connected together by an upper lateral portion and the lower proximal end regions of the stabilizing arms are connected together by a lower lateral portion. Inner sides of the stabilizing arms face each other and define a post channel that receives an elongate post. An elongate mounting member that mounts to a rung of a ladder is positioned between proximal and distal ends of the stabilizing arms and extends across the post channel.
