Abstract: A support for supporting items from an open stud wall or from an A-frame step ladder. The support includes a pair of spaced, parallel crossbars, and a support arm that interconnects the crossbar substantially at their centers and extends outwardly therefrom to define a supporting surface for supporting one or more spools of electrical wire, for convenient unreeling of household wiring during home construction. Various forms of adapters can be provided to permit unreeling wire from a spool supported for rotation about a vertical axis or horizontal axis, and for supporting other items such as tools, workbench surfaces, drawing tables, and the like. The support is of simple form, is easy to use, and is versatile to adapt to different wall and ladder sizes.
