For safety reasons, school officers must be able to see through door windows into classrooms from the hallway, but door windows must also be completely blacked out during lockdown drills. Many schools still try to keep their children safe by having them stand against the classroom walls during lockdown drills. Some schools use temporary, homemade covers for their door glass but neither of these options are the safest solution or even the most convenient.

Shelter Shutters™ is the only product that allows teachers 

to see into classrooms at any given moment and also black out visibility to dangerous intruders during lockdowns with little to no effort.

Past incidents prove that when rooms appear dark and vacant, intruders are less likely to enter, as evidenced by the Stoneman Douglas classroom shown below. The assailant was able to see children through classroom door windows and started shooting.
