Abstract: A fiber optic cable splice enclosure is disclosed, the enclosure comprising a cannister having an open end and an expansion seal assembly for closing the open end. The seal assembly includes a plurality of cable receiving ports for admitting fiber optic cables into the enclosure. The ports are in the form of slots extending inward from the outer edges of the seal assembly. The cannister and seal assembly are constructed with an oblong-round shape which provides for increased capacity of the cannister and more seal edge area for the seal assembly, allowing for additional ports as compared to a standard, cylindrical splice enclosure.

Abstract: A slot diffuser includes a pair of elongate and parallel side walls spaced by pairs of bridges. The bridges include feet that slide along receivers in the side walls such that the bridges can be positioned at any location therealong and provide support to the bridges and stability to the diffuser. The bridges include slots that extend between the side rails and that receive ends of air flow control blades. The air flow control blades include an elongate planar portion supported by rods extending outwardly on either side of the planar portions to support the blades in the slots. At a lower end of each planar portion opposite the rods is a foot that extends perpendicularly outward therefrom. Each side rail includes an inwardly projecting flange that is sized and positioned to slidably receive the foot of an associated blade such that the blade may be manually moved both within the slot and along the flange to properly position the blade during the installation or subsequent modification.
