The Underwood Armour Plated Cabinet Fitted with 30 Underwood Watch Winding Modules, and 4 spacious drawers for non-automatic watches and jewelry items, covered in leather. The internal configuration and external finishing can be modified according to the clients specifications. The Underwood Safe uses 50mm (ca. 2 inches) armour steel plate for all of the sides, whereas the actual door uses 70mm (2.75 inches) of the same steel. Our Italian supplier advises that using this information it should be possible to confirm that an equivalent TL rating for the type of construction we are using would be a TL rating ca. TL-60 (about 1 Hour).Welded across the inside of both walls are also a series of steel rods, welded in parallel on the inside.This is so that if the walls are cut from the outside, then the cut section cannot be removed without actually cutting through the rods as well. There are also a series of shorter rods welded inside attaching the outside and internal steel walls to each other. The space between the walls is filled with cement, this adds weight to the safe and solidifies the whole construction. The safe is also fire resistant, and generally though we can say that it is definitely fire resistant to 30 minutes. LOCK SYSTEMS The safe is locked by way of triple expansion bar rods, using a key system Double Mapp A8. The key lock is manufactured by the reputable German company “Stuv”.The combination lock system is manufactured by an internationally known American company called “Sargent and Greenleaf” . The combination lock is a co-axial mounted triple disc system, the use of 3 wheels allows for the total of over 1,000,000 different possible combinations. This lock type also features an internal integral “relock” trigger, which thwarts punch attacks. To a certain extent the finishing can be customized, for example the exterior can be lacquered in a colour chosen by the client using either the RAL or Pantone colour code system, or covered by cow high leather and the leather trimmings inside can be done to match the exterior colour. External Dimensions: ca. H175 x W70 x D60 cms. Internal Dimensions: ca. H164 x W60 x D42 cms.
