Like our other ForceShield doors, the Magnum Series is designed to withstand the ravages of an EF-5 tornado, meeting FEMA 320/361 and ICC-500 standards.  But it has one unique difference - with the addition of ballistic-rated fiberglass-resin UL Level 3 panels it also offers bullet resistance. The Magnum Series door is designed to help protect its contents from theft and its occupants from both tornadoes and gunfire.
