The Granger ISS comes with a five panel FEMA 320 and FEMA 361 surpassing door.

Weighing just 1300 pounds, the Granger ISS is simple to move and install. Moving the unit is not difficult as it was created with 4 stainless steel lifting lanyards making it easy to raise and strap. This likewise enables simpler installations in smaller sized areas utilizing much less equipment compared to other shelters installation requirements.

The rotationally molded polyethylenel body of this in-ground shelter has dual wall construction giving the most durable shelter design readily offered. The 1/2" outside and 1/2" interior wall surfaces are filled with VOC free dimensionally safe foam. This assures extraordinary rigidity, unparallel performance and uncomplicated installation in virtually any kind of type of circumstance.

Though polyethylene does not lend itself to condensation issues nor is it deteriorated at all by water, the foam filling makes condensation much less likely to ever happen.

This also permits the Granger ISS to be installed in numerous locations that other shelters may be limited by. Such issues as high water tables, complicated soil issues or tight spaces are no trouble for the ISS.

Other features of the ISS are a large seating area all around the unit, a LED touch light, a ventilation system with 2 sources of air flow, easy 3 step entry, custom color doors and the simplest fastest installation available. Every Granger ISS has an unmatched lifespan of storm protection for generations.
