CRL bullet resistant 7/16" thick fiberglass panel protection is highly recommended for use in banks, security enclosures and counter protection. They meet the standards of u.l. 752 ballistic performance requirement test, as well as bullet resistant test requirements of the national institute of justice. Panels are high pressure molded into standard 96" x 48" (2.44 x 1.22 m) size sheets. Cutting and drilling can be done using commonly available tools. Their polyester laminate reinforced design provides tensile-strength, heat-resistance and perform even under high temperature. The densely packed structure of the panel exhibits an excellent capability to absorb multiple impacts from high velocity projectiles, limiting ricochet or shattering. Technical specifications Panel height: 48 in (1.22 m) Panel length: 96 in (2.44 m) Bullet resistance*: 3 s.p.s.a. Panel thickness: 7/16" (11.1 mm) Panel size: 96" x 48" (2.44 x 1.22 m) Impact velocities: 1470 ft./sec. Material: reinforced structural polyester laminate with fiberglass scrim Finish: panels may be covered with vinyl, or clad with plastic laminate Cutting: can be accomplished with a circular saw, table saw, panel saw or saber saw. We recommend the use of carbide "grit edge" blades for ease of cutting, such as CRL cat. No.'s gc703 or gj1010 Drilling: use high speed steel drill bits at a low speed DS 06/28/2016
