Abstract: A cable hanger includes a hinge section, a cable retention section and a structure attachment section. The structure attachment section includes first and second locking fingers extending from the cable retention section toward the open end of the cable hanger. Each locking member has an outwardly facing concave cross-section and is provided with a pair of locking barbs extending outwardly from the ends thereof. The barbs are dimensioned to extend over and contact the inner surface of the support structure about the attachment opening and thereby retain the cable hanger within the attachment opening. Thus, the cable hanger makes contact with the inner surface of the support structure at four (4) discrete locations.
