    Being under the ground is the safest place to be in a twister and an in-ground shelter created to safeguard you in these storms is safer than any basement. Above ground shelters are offered however being above ground simply is not as safe as being in the ground. The most fundamental part of an underground tornado shelter is the door. Doors that have been checked to withstand an F5 tornado will certainly be abler to validate that they have exceeded FEMA 320 requirements.

    The Granger ISS is a rotationally molded Tornado shelter made nearly entirely of polyethylene. The polyethylene building of the Granger ISS will last longer than other product on the market. This shelter has a double wall design which is foam filled for extra rigidity and strength. The foam also works as an insulator making the interior of the shelter more comfy. The Granger ISS has a reverse taper design which does not require the device to have an anchoring system. This indicates a quicker simpler setup which it can be installed in many areas other underground shelters would have concerns. Despite soil condition, water tables or virtually any space building, this shelter installs in 4 hours or less, seats six or even more, has a number of added security functions and has a lifetime service warranty versus material deterioration consisting of cracking, leaking, rotting or rusting. The experience and commitment of Granger Plastics Company shows in manufacturing and security standards has actually provided comfort to people throughout the world.
