The frame portion includes an elongated U-shaped section, the U-shaped section including a main section having a width slightly larger than the width of a ladder leg. Transverse side sections extend from the main section adjacent side edges thereof along substantially the entire length of the main section, the side sections having a width at least about equal to the thickness of the ladder leg. The main section includes at least one longitudinal channel section. The support portion includes a foot member extending from one end of the frame portion, the foot member being pivotally connected to the ladder leg. The foot member includes a connector section and a base section disposed on a free end of the connector section remote from the ladder leg. The affixing portion includes at least one bolt member extending through the longitudinal channel section of the main section and through a transverse opening in the ladder leg. An adjustable fastener is disposed on the free end of the bolt member to selectively secure the main section to the ladder leg. The aligning portion includes mechanism securable to the frame portion disposed closely adjacent to the periphery of the ladder leg remote from the main section. The positioning portion includes a transverse pin member extending through aligned openings in the side sections.
