In an emergency, a rapid entry system is critical to the success of first responders. Supra Lock Boxes, by Kidde, eliminate barriers, reduce injuries, and minimize property damage. Trusted for more than 55 years, our emergency key lock boxes protect a wide range of both residential and commercial facilities. In compliance with International Fire Code, these police and fire department lock boxes are mounted securely near building doors, gates, and other entrances. If an alarm sounds, emergency personnel receive immediate access to the facility – with no on-site guard needed. In addition to these rapid entry systems and components, we offer convenient-entry, outdoor key safes for non-emergency situations.
