Abstract: A first length of insulated electrically conductive wire is immovably secured to one section of an extension ladder, and has an electrical outlet on such section of said ladder; a spring-loaded, self-winding storage unit secured to another section of the ladder, may releasably, windingly store a predetermined additional length of wire when said sections are in a normal non-extended position, such storage unit affording withdrawal of such additional length of wire when the ladder sections are moved to an extended position. Hooks are secured to the ladder sections, where desirable, to hang tools.
