Abstract
A ladder accessory that is used with a ladder that extends out from the side of the ladder to provide footing for a worker. The accessory comprises an elongated rectangular open box structure defining at least one set of two parallel ladder rail channels that are placed crosswise (perpendicular) to the length of the box structure and are spaced apart a distance such that one of said channels can engage one rail of a ladder and the other channel can engage the other rail and both channels engage a rung. The rectangular elongated box defines two side walls that contain single hook key slots that can be engaged with rungs of the ladder when the accessory is placed lengthwise parallel to the rails of the ladder and, with a rung lock mechanism, can be fastened to the ladder and carried with the ladder.
