<p>An underground utility enclosure assembly with a sealed fiber distribution enclosure unit (22), includes a grade level box (24) and a removable cover (26,28) that mounts to the box. The cover includes a removable plug (32) that provides access to the interior of the box. A removed plug area in the cover allows access to utility cables contained in the box and access to the interior of the sealed fiber distribution enclosure unit mounted to the open plug area. The bottom of the enclosure includes a rigid lower base frame section (42) that removably attaches to the open plug area, and an above-ground lower base ring (54) affixed to a cable opening passing through the base frame assembly. The sealed fiber distribution enclosure unit can be removed as a unit from the cover on the grade level box, with active cables undisturbed, and moved to a remote site for making above-ground fiber optic cable splices. The sealed fiber distribution enclosure unit then can be re- installed in the cover plate, with the active cables undisturbed.</p> |
