Summary
A Knox Box is a high-security, tamper-resistant safe mounted to a building's exterior. It provides the St. Louis Fire Department with immediate access to master keys and entry codes during emergencies, eliminating the need for forced entry.

The box must be ordered directly from the Knox company and calibrated for the St. Louis Fire Department. See the document below for full information on how to complete this process.
