ABSTRACT:
A ladder supported holding tray comprises a tray assembly for releasable attachment to a step of a step ladder, or to adjacent side by side rungs of overlapping sections of an extension ladder. The tray assembly includes a container and first and second supports disposed on the container, with the first and second supports being substantially disposed beneath the container and supporting the container in an elevated position relative to the supports. The tray assembly additionally includes step engagement means. The step engagement means may typically be disposed on the first and second supports and typically comprise a concave upward sloping surface configured to releasably engage and securely hook onto a step from underneath the step. The step engagement means permit secure temporary attachment of the tray to a single step of a step ladder without the tray assembly engaging the side rail members of the ladder or other steps or rungs of the ladder.
