Abstract: The present invention relates to a foldable ladder attachment adapted to be secured to the rungs of a ladder to provide a platform for paint cans, brushes or like appurtenances or tools. The device is characterized by a novel linkage assembly enabling the apparatus to be readily accommodated to be affixed at an acute or an obtuse angle to a straight or extension ladder or inside or outside the sections of a folding ladder, without necessitating the employment of extensible stretcher mechanisms or like cumbersome devices as embodied in scaffold or platform supports heretofore known.
