Which Safe Rating
Do You Need?

UL safe ratings can be confusing. This guide breaks down exactly what each rating means, what it protects against, and which industries typically require each level of protection.

Understanding

How UL Safe Ratings Work

Underwriters Laboratories (UL) is the gold standard for safe certification. During testing, trained technicians use real burglary tools — drills, saws, pry bars, and in TRTL ratings, oxy-acetylene torches — to attack the safe for a specified duration. If the safe resists breach for the rated time, it earns the certification.

The rating format tells you three things: what attacks (TL = tools, TRTL = tools + torch), how long (15, 30, or 60 minutes), and how many sides (no suffix = door only, x6 = all six sides).
