ABSTRACT:
Independently adjustable ladder extensions for use with folding, step, or extension ladders includes at least one pair of ladder extensions with each ladder extension including an adjustable leg disposed within and encompassed by the lower end of the ladder side rail and having apertures that align with through holes of the side rail so that the leg can be slidably adjusted within the side rail and then locked in the desired position for stabilizing and leveling the ladder on an uneven surface. A locking pin inserts into the through holes of the side rail and through the apertures of the leg for locking the adjustable leg in the desired position, and the locking pin includes a flap member for holding the locking pin on the side rail. A traction foot is pivotally mounted to the bottom of each adjustable leg to facilitate the stabilization of the ladder on the uneven surface.
