ABSTRACT:
An attachment for the top end of the ladder that maintains the top end of the ladder away from a vertical wall surface against which the ladder would ordinarily rest. The attachment has a general U-shape forming a pair of spaced apart legs each of which are laterally spaced from a side edge of the ladder. Each of these legs terminate in foot pads with these foot pads including an impaling device. Each impaling device is designed to penetrate a short distance the vertical wall surface when the weight of the human being approaches the upper end of the ladder. Each foot pad section includes retraction structure to retract the impaling device prior to usage. The legs are adjustable in spacing relative to the ladder. The attachment is pivotable between a forwardly extending position and a rearwardly extending position. Locking devices lock the attachment onto a rung of the ladder.
