The best thing about Pentagon’s Storm Shelters, Walk in gun valts or Large gun safes is that they are DOJ APPROVED SAFES. Storm shelters only get used once or twice in a lifetime. But our Storm Shelters are like Walk-In Vaults. They can secure your family’s belongings year-round. Our competitor’s Storm Shelters are not security products. A burglar can knock off the lock and break into the door. Not our Storm Shelters! We’ve never had one broken into EVER. The reasons: 2 re-lockers and a 3/4″ STEEL protective frame that makes it nearly impossible to pry. Our customers include: FBI, CIA, Homeland Security, US Secret Service, Quantico, and hundreds of government and police stations all over the USA.
