Belden 6304FE 877 is a plenum-rated (Plenum-CMP) security & sound cable with 6-18 AWG stranded bare copper conductors, Flamarrest® insulation, and a Flamarrest® jacket with ripcord. It uses an overall Beldfoil® tape shield with a drain wire to help reduce interference in noisy environments. Designed for indoor - plenum and indoor installations, it includes sequential footage marking every two feet for easier measuring and pull management.
