Our EF5 certified above ground safe rooms are entrapment proof, re-locatable, and can be installed on any standard concrete slab of adequate mass or geometry. They can easily be installed in a walk--in closet, spare bedroom, or the garage. Since they bolt together they can be totally disassembled from the inside, rendering them entrapment-proof regardless of door swing. We include 2 shiny 9/16” end wrenches with every storm shelter, zip tied inside for emergency egress. You CANNOT get trapped inside a Tornado Alley Armor Safe Room. Plus they are totally re-locatable and fit entirely in a van or pickup. Easy D-I-Y or Professional Installation available. We ship nationwide!
