Audio/Video installations in educational and commercial settings often require in-wall rated cable. Our CMG-rated line was specifically engineered to meet this requirement while overcoming common challenges faced by installers in these environments. Low-Profile connectors (1.25 in total depth) save valuable space in the gang box, while the rounded shape accommodates smaller monitor mounts so that the cable can be easily hidden from view.Specifically designed to support RS-232/Serial communications, this cable is fully shielded to prevent unwanted EMI/RFI interference. The fully molded cable design delivers excellent strain relief, while connector thumbscrews provide a quick and easy connection every time.The transmit and receive signals are crossed to ensure proper data transmission.
