Abstract: A lethal threat protection system for a vehicle, each side of the vehicle having an A pillar and a B pillar and a vehicle body positioned outwardly of the A pillar and the B pillar, the vehicle including a rocker panel area below and spanning between the A and B pillars and including a roof line area above and spanning between the A and B pillars, comprises a perimeter inner layer adapted to be mounted to the vehicle body and comprising an inner monolithic ballistic metal plate having a door opening and including portions adapted to overlie the A pillar, the B pillar, the rocker panel area, and the roof line area, a perimeter outer layer removably mounted to the perimeter inner layer and comprising an outer monolithic ballistic metal plate having a door opening and including portions overlying the portions of the inner monolithic ballistic metal plate, the perimeter outer layer further comprising ballistic fiber secured to an inner surface of the outer monolithic ballistic metal plate, and an armored door mou

Abstract: The present invention is directed to improved fasteners for securing insulation to a supporting structure, to a method of using the fasteners, and to combination wall structures obtained by such use. The fasteners are adapted to facilitate the securement of relatively thick insulation to a supporting structure, particularly where the supporting structure consists of a relatively hard material, such as aged concrete of high compressive strength.
