Nightlock has designed a simple but powerful solution to make classrooms safer during emergencies. Their barricade system locks directly into the door and floor, preventing forced entry, while a built-in safety shade blocks visibility from the outside. Already used in schools across the U.S., Nightlock’s barricades help turn classrooms into secure shelters, giving students and teachers critical time to stay safe. The same technology can also be installed in homes for extra protection.
