Choosing a UL 752 level is not about picking the highest number; it is about matching the panel to the threat your opening actually faces. A convenience store at street level faces a different risk than a courthouse entrance, and over-specifying wastes budget while under-specifying leaves a hole.
The levels in plain terms
- Level 1 – stops .22 and 9mm handgun rounds; typical for cashiers and reception.
- Level 2 to 3 – stops heavier handgun rounds such as .357 and .44 Magnum.
- Level 4+ – moves into rifle threats, rising with each level.
- Level 5 to 7 – high-power rifle rounds for courthouses and critical sites.

How to make the choice
Start with the threat assessment for the site: what firearm and round is the opening most likely to face, from what range? Match that to a UL 752 level, then select a polycarbonate build that meets it. RP River People supplies ballistic polycarbonate panels for the chosen level and explains the mapping; for the full level-by-level detail, see our guide on UL 752 ballistic ratings explained.
