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 . a wire form transition to which the secondary hanger is secured by the splice clips includes bendable components and can be used to form curves , elbows , changes in elevation , or tees , and the like .
