NATIONAL LAN & Premise Cables provide robust solutions for commercial enterprise networks to connect people, information and technology. Typically constructed with twisted pairs, premise cables provide performance up to 10 Gigabit Ethernet and beyond.

Category 6 Shielded 550MHz Plenum - 1000Ft.

Excluding Sales Tax

    Proudly made in New York, USA, our factory produce high quality wires and cables since 1972


    No. 23 AWG copper conductor insulated with FEP. Two colored
    mated insulated conductors twisted together to form a pair and
    four pairs assembled around a pair separator to form a core.


    The core is shielded and jacketed with a low smoke, flame retardant
