The Knox Standpipe Lock protects standpipes, fire and wall hydrants from accidental damage, vandalism, and physical attack. Since the Knox Standpipe Lock holds water pressure, it can be installed on hydrants. The Knox Standpipe Lock is available for 2.5” connections with varying thread options and is operated with a Knox FDC Wrench controlled by the Fire Department.

This product must be installed by Authorized Fire Department representative or Fire Department-Authorized Contractor only. This is a security product that requires a special fire department keywrench to lock the cap in place. Unauthorized installation may result in improper locking of the cap. An improperly locked cap may be subject to removal by unauthorized personnel.

Over forty years ago, a unique concept in rapid access for emergency response was born. The KnoxBox®, a high-security key lock box, was designed to provide rapid access for emergency responders to reduce response times and protect property from forced entry.

Today, one revolutionary lock box has grown into a complete system providing rapid access for public safety agencies, industries, military, and property owners across the world. The Knox Company is trusted by over 14,000 fire departments, law enforcement agencies, and governmental entities.
