KNOX® FDC Caps & Plugs

Fire Department Connections (FDCs) are the access point for firefighters to supplement a building’s fire sprinkler system during a fire. The Fire Department’s ability to protect your building during a fire is threatened when your building’s FDCs are damaged, blocked with debris or missing due to theft.

Benefits of installing KNOX FDC Plugs and Caps:
• Protect your fire sprinkler system against vandalism
• Assure clean fire department connection lines
• Reduce sprinkler contractor service calls to flush system
• Lower cap replacement costs with a one-time purchase
