Abstract: A plastic tab for indexing or marking a folder or an edge portion of an article such as an organizer or storage system. The lower portion of the tab has two downwardly extending walls, between which an edge of the folder or other article may be placed. The downwardly extending walls are configured and adapted to create an interference fit when the folder or other article is inserted between the walls of the tab. The interference fit enables the tab to remain securely in the desired position along the edge portion. The tab is made of a flexible polymeric material so that it may be mounted, re-positioned or removed easily. Removal of the tab from a wall edge causes the walls to flex apart and thereby eliminate or minimize the interference fit between the tab lower walls and the article on which the tab is mounted. Removal of the tab is therefore a smooth and simple operation that minimizes breakage of the tab or damage to the folder, organizer or storage medium.
