Every class room needs this type of door.
The easy slide door automatically locks into the floor.
The slide groove channel in the floor prevents any pushing from the outside.
As stated, once you slide the door 6" over the class room door's hinge, you instantly help prevent the class door from opening.
The person sliding the door shut is doing it from the side and not from in front. Saves lives.
The back of the sliding door is light weight steel armor plate.
We are also interested in establishing protected areas for individuals promoting the 911ip system iin your area.
