[57] ABSTRACT
A one piece adhesive extension tab for forming a cantilevered extension along one edge of a folder. The tab includes an elongated planar member defined by first and second longitudinal edges, first and second lateral edges, and first and second surfaces extending between the edges. A fold line runs parallel to the first and second longitudinal edges to divide the elongated planar member into first and second longitudinal sides. The planar member is foldable along the fold line to form the tab. A visual alignment mechanism is formed on the planar member for facilitating straight and uniform positioning of the tab on the edge of the folder by aligning with the edge of the folder. The visual alignment mechanism includes an opening for viewing the edge of the folder, and a longitudinal line extending from the opening and parallel to the fold line for aligning with the folder edge viewed through the opening. A third longitudinal edge of the planar sheet also aligns with the folder edge. A fourth longitudinal edge formed on the planar member defines a portion of a cutout which receives the folder side walls of expandable pocket folders.
