The Knox-Box® Rapid Entry System is a proven system of high security products that reduces response time, property damage and the liability for lost keys. The system has grown to include locking FDC plugs and caps providing protection to the intake and discharge sides of water-based fire protection systems and the Knox DrugBox. Throughout North America, more than 13,500 fire departments and emergency agencies have depended on Knox products since 1975.
More than forty years after the Knox System was first introduced, the demand for high security rapid entry continues to grow. Knox is proud that most of the original Knox-Box key boxes are still in service today.
