The most common level we get requests for is UL 752 Level 3, but each building owner or facility manger must determine what level they want to shield against as UL 752 ratings extend from Level 1 to Level 8.
UL 752 Bullet Resistant Levels 1 through 3 meet the needs of most commercial properties such as Convenience Stores, Pharmacies, Banks, Schools, Universities, Police Stations, Hospitals, and others as they are designed to withstand shots from handguns commonly used in robberies or small arms attacks.
UL 752 Bullet Resistant Levels 4 through 8 are designed specifically to withstand assault weapons or military rifles and are typical only installed in military or government facilities such as Embassies, Government Buildings, etc.
