ABSTRACT:
A versatile, easy to use, adjustable tool, paint, accessory and supply caddy for use on an extension ladder. The caddy can be used on ladders having rungs that are either round in cross section or have steps that are flat and more rectangular in shape. Upper and lower mounting cradles attach to any consecutive rungs of the extension ladder at two separate attachments points. A quick release, spring loaded clamping mechanism allows the ladder caddy to be quickly and securely attached and then removed from the ladder, with the upper and lower mounting cradles adjustable to accommodate different ladder rung/step shapes as well as diameters and distances between rungs. Paddle shaped trays can be locked in place on the caddy in a variety of positions, and the trays can swing over or under each other or be swung in opposing directions away from the ladder user thereby creating a useable work space adaptable to almost any ladder position.
