Justin Rivard is a high school senior at Somerset high school and as part of his senior project, he invented a lock that can be used to stop an intruder from accessing the classrooms. It's a type of lock that's also a doorstop that stops an intruder from accessing the room.
He saw that intruders were able to push their way through in-swinging doors during the training on how emergencies are to be handled. ALICE stands for Alert, Lockdown, Inform, Counter, Evacuate, which is done for active shooter response training in schools.
Made of steel plates and connecting rods, Justin’s device slips beneath a classroom door and latches to the door’s jam.
The product is called JustinKase and it's already picked up some interest from other school districts.
