Abstract: A telecommunications closure includes a base interface (10) for supporting the closure (60) during assembly, or repair, or later servicing, or installation, or as a permanent mount. The base interface (10) includes structure for mounting to cables, structure for mounting to elements for connecting to the interior elements of the closure (60), and elements for mounting to an interface support. A support device can be used as a workstand, a lift device, a pole mount, a wall mount or another mounting system.

Abstract: One or more seal retention clips can be used to retain a perimeter seal within a perimeter groove defined by a fiber optic enclosure housing. Certain types of seal retention clips can include portions that embed or bite into the housing of the enclosure, and/or embed or bite into the perimeter seal.
