The Knox HomeBox allows Emergency First Responders quick access to your home for an immobilized patient, without damage to the property. Knox Boxes are available for purchase through the Knox Company at https://www.knoxhomebox.com/.
Click on the “Order” tab, then enter your state and city. Each community is keyed differently and only the Fire Department has the key. These residential lock boxes now come in three different colors and can either be hung over the door or mounted to a wall. Prices range from $159 for the wall mount and $174 for the door hanger.
