Abstract: An upper portion of an aisle containment system for a data center. The upper portion includes spaced vertical supports aligned in two parallel rows and horizontal supports that extend between and are connected to adjacent vertical supports to form the basic framework of the upper portion. The upper portion also includes (1) at least one pair of arms that extend outwardly from opposite longitudinal sides of the basic framework and are configured to support services and (2) at least one busbar casement that is attached to the vertical supports and extends substantially the length of the upper portion. Each arm of the at least one pair of arms includes a segment that is rotatable between a first position in which the segment is substantially parallel to the vertical supports and a second position in which the segment is substantially perpendicular to the vertical supports.

Abstract: A ceiling tile clip includes a top wall, a pair of parallel, spaced side walls that extend downwardly from opposite edges of the top wall and flanges at lower edges of the side walls that extend outwardly. The top wall includes a threaded opening in the center thereof. The ceiling tile clip is configured to be attached to an elongated ceiling grid member by a threaded member that threadedly engages the threaded opening. The elongated ceiling grid member has side surfaces and lower flange portions. When the ceiling tile clip is attached to the elongated ceiling grid member, the top wall of the ceiling tile clip is above the elongated ceiling grid member, the side walls of the ceiling tile clip are alongside the side surfaces of the elongated ceiling grid member and the flanges of the ceiling tile clip are above the flange portions.

Abstract: An access floor panel assembly including (1) a plurality of access floor panels arranged edge-to-edge and (2) a plurality of spaced pedestals. The plurality of access floor panels are positioned above a subfloor by the plurality of pedestals. Each of the plurality of access floor panels includes (1) a support layer and a floor finish layer on top of the support layer and (2) four edges. At least one of the four edges has a tongue connector or a groove connector, which are configured to form a tongue and groove connection when joined. Each of the tongue connector and each of the groove connector is formed by the support layer and the floor finish layer.

Abstract: An elongated ceiling grid member and a ceiling grid assembly that includes a plurality of the elongated ceiling grid members are disclosed.
