ABSTRACT:
This invention relates to an improved safety platform for attachment to a ladder. The locking means of the device is engaged and disengaged without the use of tools or complicated mechanical means. This enables the user to adjust the height of the attachment on the ladder while standing on the ladder above ground level. The platform of the invention is fixed in a generally horizontal plane to hold containers or like articles, or for use as a platform for a person to stand upon while working. The invention is ideally suited for use by painters and like persons who do exacting work at varying heights above ground level while standing on a ladder.
