Abstract: A cable support system provides the organization and support for bundles or runs of communication or database cables, for example, avoiding the mess usually associated with the distribution of such cabling. The system is designed to be a low cost and easier to install tray, supporting runs or bundles of cable from a building structure such as a structural ceiling, beam, girder, or purlin, and above a suspended acoustical ceiling. The system is suspended by common threaded rod which supports a primary hanger having a generally rounded support symmetrically below the rod with one side openable so that a secondary hanger may be inserted in and fastened to the inside of the support. The secondary hanger is formed from a roll of flexible open plastic mesh having oriented strands secured to the inside of the primary hangers by spring clips. Plastic splice clips may be used to join lengths of such mesh, or may be used in the fabrication of various transitions or branches.
