Petruccelli L.T.D of North America says; Be on the lookout for safe sellers that list just ‘door thickness’ rather than the barrier material type and thickness as this is a recent trick many underhanded safe marketers employ. By listing the total thickness of the safe door including the safe dial, barrier material, airspace, inner bolt work, etc.... the provided figure can sound quite impressive while actually preventing the buyer from obtaining any solid information on how thick the barrier material actually is or what it's made of.
