Abstract: A combination (i) roller seat and (ii) tool and material carrier is preferably used with a hollow body tool and material holder detachably mountable to the upper region of an open step ladder. The combination roller seat and carrier has a substantially planar base with a structure in the shape of a truncated frustum attached to and extending above the base, this structure occupying a same shape and volume as does a truncated frustaconical upper region of a open step ladder. Wheels to the base permit a person to sit upon the top of the structure while the base rolls upon the wheels, making thereby a roller seat. When the hollow body tool and material holder detachably mountable to the upper region of the open step ladder is alternatively mounted over the structure, the structure serves at least indirectly to hold any tools and materials that are also held by this hollow body holder.

Abstract: A tool and material holder fitting to the top of a step ladder has an extremely large number of pockets, cavities, loops, clips, hangers, hooks and the like which securely hold a great variety of power and hand tools, caulking guns, paint brushes and paint pads. A major loop maintained open by an insert with a shape memory holds a large paint pail, bucket or can, and is optionally re-sizable to hold one or two smaller cans. A shallow reservoir on a top panel overlying the top step of the step ladder holds small items but still permits standing on the top step.

Abstract: A tool and material holder fitting to the top of a step ladder has selectable detachable panels having and presenting an extremely large number of variously selectable pockets, cavities, loops, clips, hangers, hooks and the like which securely hold a great variety of power and hand tools, caulking guns, paint brushes and paint pads. The holder is stiffened by internal tubes and sheet preferably made from strong shape-retentive plastic, and will stand upright upon the floor. A major loop maintained open by an insert with a shape memory holds a large paint pail, bucket or can, and is optionally re-sizable to hold one or two smaller cans. A shallow reservoir on a top panel overlying the top step of the step ladder has a magnetic bottom for conveniently holding small ferrous items. A detachable strap and shoulder harness permits great loaded weight to be conveniently and safely carried.
