Knox Box Storz 5" Locking Cap

The 5" Knox Storz Lock® is operated with a Knox FDC Wrench controlled by the Fire Department. To ensure the Knox Storz Lock® properly fits, the Knox Company strongly encourages the use of connections that meet the adapter specifications. The Knox Storz Lock® protects large diameter Fire Department connections (FDC) from accidental damage, vandalism and physical attack. Since the locking cap holds water pressure, it can be installed on hydrants. The Knox Storz Lock® has been designed for ease-of-use when installing or removing the cap from a connection. The locking cap can be quickly installed or removed with a Knox FDC Wrench and a standard spanner. Authorized by 2018 IFC1 and IBC2 (Chapter 912.4.1) and 2018 NFPA 13 (Chapter 13.1.13).  Also enacted in 2003, 2006, 2009 and 2012 (Chapter 912.3.1) and 2015 (Chapter 912.4.1) of IFC editions.
