A cable rack arm and support system suitable for underground power and communication service is made from a non-metallic polymer that will not rust or corrode. The cable rack arm is adapted for mounting to existing underground stanchions or for stanchions of a more modern design. Each cable rack arm is securely mounted to the stanchion. Each cable rack arm then supports one or more cables in cable rests or saddles molded atop the arm, thus keeping the cables accessibly organized in a manhole, tunnel or vault. Plastic cable ties may be used to secure the cables to the cable rack arms. Nonmetallic pins may also be used to secure the cable rack arms to the stanchions. The stanchions may be made of nonmetallic composite material that includes a fiberglass cross-layered knitted apertured mat for increased strength.
