Knox Box Information

What is a Knox Box?

The Knox Box is a box that contains keys to the structure so the Fire Department can access an emergency area quickly, without causing property damage.  This system saves valuable time that can be wasted while the Fire Department waits for a property owner to arrive and unlock their building. The box itself is very secure and very durable.

Advantages:

  • Allows the Fire Department quick access to restricted structures.
  • Prevents expensive damage to entry systems at prescribed businesses.
  • The Knox Box is considerably cheaper than damage that may occur to a business. Most insurance deductibles do not cover damage under $500.
  • Waiting for a business contact to arrive can provide long delays, if they can be contacted at all.
