Abstract: A ladder stabilizer assembly for stabilizing a ladder is provided. The stabilizer assembly comprises a telescoping stabilizer pole which is attached at its upper end to the upper portion of the ladder side frame. The lower end of the stabilizer pole can be pivoted in two ways: away from the ladder side frame and within a plane which is parallel to the plane of the ladder side frame. The stabilizer pole has an inner member which slides within an outer member so that the stabilizer pole can be extended outwardly in telescope fashion. The inner member has a cam mechanism at the end which is within the outer pole member. The cam mechanism consists of a first rubber plug rigidly attached at the end of the inner member and a second rubber plug swivilably attached on a axis which is parallel to but not coincident with the longitudinal axis of the two plugs. The cam mechanism allows the inner member to be locked relative to the outer pole member by rotating the lower-most stabilizer pole member by about 90.degree..
