Classroom Safety Device "The Sleeve"

The American made Sleeve is made out of light weight solid carbon steel, making it easy to deploy effectively and quickly. The safety provided by the Sleeve comes from being able to secure the classroom from inside by simply sliding the Sleeve over the door closer. This keeps the teacher inside the classroom with the children vs. having to go into the hallway to lock the door (most classroom doors only lock from the outside) where the active shooter or violent intruder is patrolling.
