ABSTRACT:
A ladder anchoring system, using a ladder having a pair of side rails and rungs extending between the side rails. The side rails each have a central portion and a pair of flanges. The side rails have an inner side where the rungs are attached, and an outer side. A spike assembly is mounted to each of the side rails, between the flanges and the outer side. The spike assembly includes a spike which is mounted for slidable movement such that it selectively extends below the ladder bottom so that it may extend into ground below the ladder, and selectively does not extend below the ladder bottom for safe storage and transportation. A kick plate mounted to the spike facilitates penetration of the spike in the ground.
