Bulletproof Protection Levels

Security levels for bullet-resistant systems have been established by UL (Underwriters Laboratory), the primary testing organization for materials used in these systems. Each level has been tested and found effective at stopping certain types of projectiles, ones most typically employed during an armed robbery. While ratings extend to Level 8, the needs of most banks, credit unions, and convenience stores are well covered in Levels 1-3.
