RETAINER TAB ASSEMBLIES AND SLACK BASKET SYSTEMS, FIBER OPTIC ENCLOSURES AND METHODS INCLUDING THE SAME

A multi-drop closure system for containing and managing a bundle of optical fibers includes an enclosure and a slack basket system. The enclosure defines a slack basket chamber to hold the bundle of optical fibers. The slack basket system includes a retainer tab assembly mounted in the enclosure. The retainer tab assembly includes a tab member movable between: an open position, wherein the tab member is positioned to provide more open access to the slack basket chamber and thereby enable the bundle of optical fibers to be more easily inserted into, removed from, and/or manipulated in the slack basket chamber; and a retaining position, wherein the tab member overlaps the slack basket chamber to retain the bundle of optical fibers in the slack basket chamber.
