Abstract: A cable retaining apparatus for retaining and routing lengths of cable on an assembly structure is provided. The cable retaining apparatus includes two or more adjacent retaining members extending from a surface of an assembly structure. The retaining members each have at least one retaining surface oriented such that each retaining surface faces the retaining surface of an adjacent retaining member forming a cable channel therebetween. The retaining members also include one or more protrusions extending from each of the oppositely facing retaining surfaces into the cable channel in a staggered or offset orientation. This configuration allows one or more cables to be routed within the cable channels and retained therein by the lateral retaining forces applied to the cable from the plurality of protrusions.
