U.S. Storm Shelters Personal Safe Rooms

Mighty Mite Safe Rooms


For many years, we have had requests for a small, basic personal safe room that could fit in most closets and still deliver the safety and security of our larger tornado shelters.

The Mighty Mite safe room is designed for rugged protection with the same EF-5 certification as our largest shelters. This line offers excellent safety inside your home, office or garage with a small footprint and a more affordable price.

U.S. Storm Shelters "Mighty Mite" Safe Rooms Fit Your Space

Home Loan Pros Financing

Built with the same high strength materials as our standard safe rooms but with outside dimensions of only 26 1/2" inches x 38 1/2" inches, the Mighty Mite I offers excellent protection for 2 standing adults. The Mighty Mite II is slightly larger with outside measurements of 34 1/2" inches x 46 1/2" inches for 3 standing adults. The largest, Mighty Mite III (our most popular safe room) has exterior dimensions of 38 1/2" inches x 50 1/2" inches allowing for 4 standing adults. All U.S. Storm Shelters safe rooms have an exterior height of 7 ft.

Due to their small size, the Mighty Mite doors open to the exterior. Because of this design requirement, each unit comes standard with an emergency exit wrench stored inside the shelter. The entire safe room can be disassembled from the interior should the door become blocked by debris following a storm. When closed, the door is secured by its two deadbolt locks plus three stainless steel tubular cross bars set into a system of welded brackets.

All Mighty Mite safe rooms are anchored using the same Hilti® system used on our larger, full size safe rooms. The Mighty Mites come standard with an interior, battery operated LED tap light as well as dual, identically keyed Kwikset deadbolt locks.
