Detailed Description

Referring now to the drawings, an enclosure 10 is shown to include a base 12 and a removable cover 14. Disposed within the enclosure 10 is an interior 16 for holding the organizing member 50 and telecommunications cables and equipment, such as splices, splitters, connectors and adapters, and cable slack storage.

The cover 14 is mounted to the base 12 by a hinge 20 and a latch 18. The fasteners 140 may help secure the cover 14 to the base 12. Disposed between the base 12 and the cover 14 is a seal 30. At one end of the enclosure 10 are a plurality of ports 40 that seal around

cables

180, 182 entering and exiting the interior 16 of the enclosure 10. If there is no cable in the port, a plug may be used.

The organizing member 50 includes a master tray 52 having an upper portion 54 and a lower portion 56. The master tray 52 is mounted to the base 12 by a hinge 58 along a side 60 of the base 12.

The upper portion 54 of the master tray 52 includes a distribution area 70 for holding fiber optic connectors and

adapters

94, 96. The tower 72 is mounted to the main tray 52, for example by a snap fit. The tower 72 defines a central opening 74 for allowing passage of cables to other areas of the organizing member 50. Mounted to the tower 72 may be a plurality of trays 80 mounted to the tower 72 by hinges 82. The tray 80 may include fiber storage, splices, splitters, and/or connectors and adapters.

The lower portion 56 of the master tray 52 may include one or more desired functions, including splices 90, splitters 92, and connectors and
