ABSTRACT:
An improved device for safely and effectively securing and stabilizing a ladder placed against a structure and resting upon the ground. The device includes a U-shaped member forming an anchoring pin, an impact area for receiving a driving force, and a handle for easy disengagement of the anchoring pin, for simultaneously engaging both the lowest rung of the ladder and the ground to prevent the ladder from inadvertently displacing across the ground away from the structure. For optimum safety, at least one anchoring pin placed across the center of the lowest ladder rung, or a pair of anchoring pins placed on opposite sides of the lowest rung will secure the ladder against lateral displacement and side-to-side tipping forces.
