The door has a total thickness of 6 1/2" (165 mm), with a total solid metal thickness of 1" (25 mm) over the lock and vital portions, the hardened drill resisting steel plate being embodied between two steel plates. The outer body and the back plate are electrically welded to form a one piece unit, the space between the outer and the inner steel plate bodies incorporating the hardened drill resisting steel plate and our special heat insulating material. The body is of 24 bend construction, the door frame and locking rebates being an integral part. The total thickness of the body is 4" (102 mm) to 4 1/2" (114 mm). In spite of their massive construction, the safes are of attractive design and the smoke grey enamelled finish is in equal harmony with traditional or contemporary furnishing of offices.ĭesigned by specialists in the manufacture of security and fire-resisting equipment and backed by the experience and knowledge gained in over 140 years of safe and strong room making, these Chatwood-Milner safes give protection against burglary and fire at a moderate cost. The Chatwood-Milner fire-resisting material used in the construction of the safe has been tested and proved in many actual fires. The locking mechanism and boltwork are of the latest improved Chatwood-Milner design and an automatic relocking device gives protection against explosives. These safes embody special features, one of which is the incorporation of drill-resisting hardened steel plate between the inner and outer steel plate bodies of the safes, the door having similar protection. This new addition to the famous Chatwood-Milner Duplex range of safes has been designed to give particular security against attacks by drills and explosives, and provides protection against fire and the attendant risks of fall, impact and crushing from the collapse of buildings.
