The Shield Fortress Series was tested at NTS Chesapeake in Belcamp, MD and Intertek in York, PA to the US State Department (DoS) forced entry standard at the 15 minute level (FE 15) and at the iFT Rosenheim laboratory and was awarded a resistance class 4 (RC 4) rating. This certifies that the Shield Fortress series can withstand entry from highly skilled attackers using heavy-duty tools such as crowbars, sledge hammers, axes, wedges, saws, steel cutting pliers, and power drills. The Fortress was also tested for bullet resistance to UL752 levels 3 and 8, NIJ levels III and IIIA, and European standard EN1522 levels FB4 and FB6. The door is suitable for government offices, commercial buildings, private homes, and apartments.
