Abstract: An accessory device capable of being mounted on a ladder having hollow rungs includes a pair of primary support arms which are shaped to fit within rungs having flat top sides to prevent rotation of the primary arms therein. Secondary support arms are slidably extensible from the primary support arms to laterally position a tray assembly relative to one side of the ladder. A brace connected to the secondary support arms engages a tray assembly. The level of the tray relative to the slope of the ladder is adjusted by varying the position of arcuate slots found within a pair of flanges mounted on the bottom side of the tray relative to the brace. Thus, a user can adjust the level of the tray while keeping one or both hands on the tray for stability. The device may be mounted to either side of the ladder with the supporting arms and brace optionally remaining mounted on the ladder during transport and/or storage.

Abstract: A pair of attachments for use with ladders constructed with hollow rungs to stabilize the ladder and to protect the gutter. These attachments when used with ladders also provide for a scaffold plank. The attachments when used with a ladder on a pitched roof allows the ladder to be used to access that roofs peak. Previously the ladder would rest on the rain gutter when the user was to access the roof of a building. Previously a work platform had to be built from wood or metal resulting in time consuming construction. Previously when accessing the roof peak of a building a means of providing a positive foothold had to be constructed from rope and ladder or from wood. The present invention provides steel flat bars bent to fit the rung spacing of the ladder with a steel tube welded at each end sized to fit snuggly into the opening of any two consecutive rungs in that ladder. The ladder can now be used to access the roof of a building without resting on the gutter.
