Abstract: A sleeve fits securely over a ladder rail with attached hooks over at least two rungs of the ladder. Interchangeable hook components may be rounded recessed hooks for extension-type ladders or flat angled hooks for step ladder. The hook components are adjustably attached to the sleeve. Brackets for utility attachments are pivotally secured to the sleeve with two bolts through a half circle slot and central hole through the sleeve. Paint buckets, paint trays and utility trays may all be pivotally attached. A hand railing, safety railing support and holder for paint brushes and other tools may also be attached.

Abstract: A sleeve fits securely over a ladder rail with attached hooks over at least two rungs of the ladder. Attached to the side of the sleeve are a rigid hand rail and pivotable utility tray. Clips on the side of the tray hold tools. Supplies and tools are stored in the tray or the tray may be a paint roller tray. A slot or groove in either the sleeve or an extension of the tray permits tilting of the tray to a desired angle relative to the ladder. A bolt through one of the hooks secures the sleeve in place and permits the sleeve to be used upside-down on an opposite ladder rail. The sleeve may be constructed from a single sheet of material cut and bent into shape.

Abstract: A combination bracket and adjustable ladder tray for holding the tools and materials of a tradesman in close proximity to his area of work while he is working on an extension ladder. The device of this invention includes a tray contoured to fit the most commonly used tools and materials of the tradesman, apparatus for securing these tools in said tray and a support bracket which on one side is adjustably secured to the base of said tray and on the other side has provision for secure attachment within the hollow rungs of an extension ladder. The tray is adjustable so that it can be always level relative to the ground or in any other angular position, regardless of the angle at which the ladder is placed against a structure.

Abstract: Parallel tubular arms removably slide into the openings through the openings in the side rails and the hollow rungs of aluminum ladders. A swivel on at least one arm protruding through both ladder rails turns to secure the handrail to the ladder. Orthogonal extensions of the arms support the handrail in a fixed position away from the ladder. Depending on the relative lengths of the supports the handrail may be in parallel or sloping alignment with the ladder. Handrails may be installed on both sides of the ladder and a restraining means secured between the handrails.
