TANN Bankers Cash Safes MK 4
John Tann Bankers' Cash Safes are maximum-security safes. The techniques gained from 170 years of safe making have been used to incorporate many features of the world-famous John Tann Treasury Doors. Resistant to such modern forms of attack as the Oxy-arc, as well as older devices such as drills and explosives, these safes are designed for the heaviest risks.
Bankers' Cash Safes are resistance in depth.
The Body has an outer shell of toughened steel, bent cold and welded to form a complete jointless unit. This encompasses a 3"thick monolith of anti-blowpipe Adamantium, backed by 1 "of Tannalloy, a material which gives improved security against all forms of drilling and oxygen cutting.
The Door is welded to form one massive construction with 1" layers of both Adamantium and Tannalloy on either side of a heat-dispersing copper sheet. The minimum protective thickness of the door at any point is 4". Additional protection is provided at the vital parts of the lock chamber.
1 1/2"diameter steel bolts pass through the solid flange of the lock chamber into the body of the safe. A full length 1 1/4 "steel tongue-bar secures the back of the door. If the locks are destroyed by heat, explosives or any combination of these and other methods, the bolts are automatically held and doubly secured in the locked position. Practically, the whole door—not merely the locks—would have to be destroyed to gain entry.
Where there is a severe fire risk (unique documents, objets d'art, etc) additional fire protection is available in a 1 1/4" thick lining of John Tann fire resisting material. Besides forming an excellent heat insulator, it gives off moisture when heated - an added defence against charring and distortion.
