Technical Examples

An elevated raceway for routing utility lines in a vertically spaced relationship above the upper edge of a partition. The raceway includes an elongated passageway configured to retain utility lines in a horizontally extending manner. A first support member extends downwardly from the raceway, and has a connector spaced apart from the raceway a first vertical distance. The connector is configured to attach to a partition frame. A second support member extends downwardly from the raceway, and has a connector spaced apart from the raceway a second vertical distance that is different from the first vertical distance, such that the raceway is supported at a generally uniform vertical height above an upper edge of a partition having sections with different heights.
