RACEWAY CONSTRUCTION FOR PANEL

A raceway structure which is fixedly attached to and extends longitudinally along one horizontally extending edge of a panel assembly. The raceway structure includes a U-shaped channel member which resiliently but releasably snaps into engagement with longitudinally spaced supports which are fixed to and project downwardly from the bottom frame rail of the panel. The supports occupy only minimal space within the channel member. The raceway channel member is provided with increased height relative to its width to provide upper and lower interior channel regions which accommodate power and telecommunication cabling systems. The supports are releasably engaged with upper edges of the channel member and provide the primary support for securing the channel member to the panel. The supports also provide a support or backing for the side covers of the channel member at a location disposed vertically intermediate upper and lower edges thereof so that the side covers, even with their increased vertical extent, retain their desired flat vertical configuration and can withstand side impacts which are typically imposed thereon.
