Can I install a lite kit (or window) in an existing fire rated door in the field?


No, you cannot. Lite kits and other hardware preps are recorded in a logbook with the serial number of the fire label at the time the door is machined. This is to ensure the company providing the certification is following all N.F.P.A. (National Fire Protection Association) guidelines. These records are audited each month by an inspector to ensure all criteria have been followed. Contact your local IDN for details or for a quote.
