A cable hanger for securing multiple cables to support structures including antenna towers and poles. The cable hanger has a hingeably-coupled pair of shell halves with recesses that, when folded, establish a pair of cable passageways. Gripping arms provided on each of the shell halves project into a corresponding one of the cable passageways for gripping a cable positioned therein. Pairs of gripping arms located on opposite shell halves have a confronting relationship for gripping the cable on diametrically opposite side surfaces.
