The system is well thought out and well designed. I have a high level of confidence in the system preventing break-ins through any of the four doors we "armored". I did not install the brass night lock because we have ceramic tile on concrete and it seemed redundant to the double door kit. It would be the ultimate protection for anyone trying to "kick in" the double entry doors.
When installing I previously sent a suggestion that you should include (or include) a small amount of thin "seal tape" (or something) to replace the material removed to install the armor device. It is certainly not large, but we can see daylight in the area where the Armor piece is installed when the door is closed. This is not necessary, but you have thought of so many aspects of protecting against break-ins I would think that little thing would just be the frosting on the cake.
Anyway, great concept, well designed system.
