Each flat top shelter comes with a spring pressure lift door and non-skid ladder-type stairs with safety rails.
2. Safety Rating
The Texas Tech Institute Wind Engineering and Science has certified this structure to withstand an F-5 tornado. All Hausner's Storm Shelters meet Fema 320 and ICC-500 standards.
3. Interior Dimensions
For your family's comfort, these storm shelters are made with an interior height that will accommodate most people (inside height is 6'2"). To figure what size shelter you will need, FEMA guidelines suggest 4 sq ft per person so a 6x8 shelter will hold approximately 12 people. (6x8=48 divided by 4=12)
4. Water Tight
Hausner's Shelters are guaranteed not to leak for 10 years from the date of installation. This includes the seal where the two units are joined.
Hausner's includes a 6" vent, 8" turbine and stairs with double rails for each storm shelter at no extra charge!
