The only Tornado Shelter with a Safe Room/Panic Room quality door!
See the new generation of Granger ISS Tornado Shelter doors under go FEMA 320 & FEMA 361 testing at Texas Tech University's Wind Science & Engineering Research Center. The Granger ISS is an underground Tornado Shelter, so in theory, it only needed to be tested to FEMA 320 standards. Due to the high quality engineering staff at Granger Plastics, the Tornado Shelter door not only meets or exceed FEMA 320 standards, it also meets Above Ground Safe Room criteria by exceeding the FEMA 361 standards. The same door passed (2) tests, being impacted (3) times by a 15 pound 2 x 4 at 67 mph, then seeing an additional (3) impacts, by a 15 pound 2 x 4 at 100 mph. Even though the second test was unnecessary due to the Granger ISS Tornado Shelter being an underground unit, but went forward with the more grueling test anyway to display Granger's commitment to safety, innovation and quality. This is all just another example of why Granger Plastics produces the best tornado shelter available for single family consumers. Granger Plastics has been manufacturing Tornado Shelters for over 15 years currently. Even gaining international attention as early as 10 years ago from Internationally recognized publications such as Plastics News, USA Today and a number of news channels and media outlets across the country!
