Data cable installation system for pre-existing facilities includes a cable managing housing, a compressed air connection associated with the housing and a compressed air pressure directing chamber formed within the housing. A cable directing tube also associated with the system includes a cable receiving port extending through the cable managing housing past the compressed air pressure directing chamber into a data conduit interface. The data conduit interface is associated with the cable directing tube and has a larger diameter than the cable directing tube adapted to form a sealed connection with a data conduit having a diameter similar to the data conduit interface. During use, data cable is passed trough the data conduit when it is first inserted into the cable receiving port and manually feed into the cable managing housing. The air directing chamber causes compressed air pressure to assist movement of the data cable into the data conduit through the cable directing tube.
