Abstract: An extension panel for connection to a lower panel of the type having vertical uprights defining upper ends and including a utilities passageway extending along an upper edge of the lower panel for receiving utility conduits therein. The extension panel includes a pair of space-apart upright posts, and at least one beam extending between the posts and rigidly interconnecting the same. A pair of structural members extend downwardly from the lower ends of the posts to engage the lower panel and rigidly interconnect the extension panel and the lower panel. The structural members are laterally spaced-apart to define a downwardly-opening utilities opening therebetween. The utilities opening is positioned in alignment with the utilities passageway of the lower panel to permit utilities conduits to pass through the utilities opening when the extension is secured to the lower panel.

Abstract: A modular mounting system for the delivery of office utilities from a utility distribution system of an office partitioning system to a worksurface positioned in an individual workspace includes a mounting rail having an upper portion shaped for abutting attachment to a bottom surface of the worksurface and further includes a lower mounting portion defining at least one mounting aperture therein. A utility distribution bracket is abutted to the lower mounting portion wherein the bracket includes a base and an upper frame connected to the base defining therein a cavity shaped to closely receive a utility distribution block. The base and frame further define at least one aperture for user access to the utility distribution block.
