    How Do They Work?

    Fire Ttuck and Fire Hose

    In the event of a fire, Fire Departments connect to an FDC (Fire Department Connection) to supplement a sprinkler or standpipe system.


    Unprotected FDCs are vulnerable to debris and nesting animals that clog the pipes and prevent the flow of water.

    Knox FDC Locks

    Knox FDC Locks protect these connections and keep pipes clean, ensuring the maximum flow of water.


    “At Brooks Equipment, we feel strongly about helping fire departments increase efficiencies, and the partnership with the Knox Company allows us to play a role in helping both businesses and firefighters when fires occur,”
    - Robert Bell, Jr., General Manager, Brooks Equipment.
