Patent

CA 2187729

An improved replacement ladder rung/pulley construction is disclosed wherein a rotatable rod, mounted on bearings and extending substantially completely from one side of the ladder wall to the other, is located within the rung. The rung has a cutout portion proximate its center, which allows a rope to be passed therethrough and over the rotatable rod. The rod thus functions as a pulley and obviates the possibility of the rope sliding off and becoming jammed if the pulling force is exerted from one side or the other.
