Abstract
An extension pole and tool holder apparatus is described. A first rod has a distal end and a proximal end, and a first rod aperture extending from the distal end toward the proximal end. It also includes a transversely-extending aperture portion that is longitudinally spaced from the distal end. A second rod also has distal and proximal ends, the second rod being disposed in a telescoping, longitudinally-moveable arrangement with respect to the first rod. The second rod typically has a second rod aperture with a longitudically-extending aperture portion extending from the distal end toward the proximal end. A third rod has a protruding member extending transversely outwardly therefrom, the third rod being mountable within the first and second rods such that the protruding member is trapped within the transversely-extended aperture portion of the first rod aperture and the longitudinally-extended aperture portion of the second rod aperture.
