    How Do Knox® Locking Caps 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.
