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!
