Single Piece Lid System
All of our in ground FlatSafe Tornado shelters come with our patented single piece lid system. The lid is ¼” thick steel plate with added structural tubing to provide extra strength. The single-piece lid is larger than the frame of the saferoom opening and sits above the frame, not down inside the frame. Our lid system is MUCH stronger than the typical 2-piece lid system offered by everyone else and provides more than adequate ventilation to the occupants.
Our Shelters Will Never Float - Guaranteed.
FlatSafe Tornado Shelters are back-filled with ready-mix concrete to counteract buoyancy and floatation. FlatSafe Tornado Shelters will never float...Guaranteed!
