Abstract: Room dividers with a layer of porous fibrous tackable/acoustic sheet material which is sufficiently durable to serve the same function as a non-tackable/acoustic layer, yet which is sufficiently porous that it can be used as a tackable/acoustic surface. This layer can be provided over a panel core, or can be provided in the form of tiles used to cover a panel core.

Abstract: An upper stackable panel is provided for use with lower panels having a structural panel to panel, connector mount located at least at each upper corner of said lower panel, to which a panel to panel connector can be secured by at least one fastener. The upper panels have a structural panel mounting member located at least at each bottom corner, at a location adjacent an upper corner panel to panel connector mount when the upper panel is positioned on top of the lower panel. Each lower corner panel mounting member has a fastener configuration which is compatible with that of the adjacent upper corner panel to panel connector mount on the lower panel. At least one fastener secures each said bottom corner panel mounting member to its adjacent upper corner panel to panel connector mount, to create a structural connection between the upper and lower panels at each of their respective lower and upper corners.

Abstract: A raceway for energy distribution lines in which the sections of the raceway are of the knockdown type with interlocking extrusions requiring minimal use of fasteners and in which access openings and the extruded trim plates and covers interlock with selected other extruded elements to cover gaps in adjacent sections and for closures and covers for connectors and receptacles located and supported in the raceway. The raceways are secured to the bottom margin of wall panels.
