ABSTRACT:
Independently adjustable ladder extensions for use with folding, step, or extension ladders includes at least one pair of adjustable support legs slidably disposed within the channels of the side rails and having apertures that align with through holes on the side rails so that the support legs can be slidably adjusted within the channels and then locked in the desired position for stabilizing and leveling the ladder on an uneven surface. Locking pins insert into the through holes of the side rails and through the apertures of the support legs for locking the support legs in the position, and the locking pins include a flap member for holding the locking pins in position. A traction foot is pivotally mounted to a base member located at the lower end of each leg to facilitate ladder stabilization on uneven surface, and each traction foot is independently rotatably adjustable on the base member in parallel or sideways orientation relative to the sidewall of the structure while an extension member terminating with an eave catch is slidably disposed within the upper end of each side rail for supporting the ladder against a pitched roof.
