The T2 designation refers to an extended tool list (Tool List 2), added in the 2019 version of the European standard EN 1143-1. During certification, safes are tested with a standardised set of burglary tools; the T2 list includes more powerful and more refined versions of these, reflecting the equipment available to burglars today.
T2 is an optional addition to the grade, just like EX (explosives) or CD (core drilling). A safe marked Grade IV T2 on its certification plate therefore offers the same certified grade, additionally tested against heavier tools. Examples in our range include the Chubbsafes DuoForce T2 and TriForce T2, certified in Grades 4 to 6 T2. Read more on our page burglary resistance classes and test methods.
