The total thickness of the body is 4 1/2 (114 mm). The outer steel body is electrically welded to form one unit. The body of the safe has a total metal thickness of 1 5/8″ (41 mm) including 1″ (25 mm) Chatwood-Milner new special blow-pipe and drill-resisting armour cast in one piece.

The fire resisting chamber at the back is hinged and fastened with screws (if combination locks are fitted, the chamber is secured by a key lock with keys in duplicate).

The door is securely held in its seating by steel sliding bolts 1 1/2″ (38 mm) diameter, all fully protected by the armour of the body when the door is closed. The number of bolts varies from eight to twelve according to the sizes of the safes

The sliding bolts are controlled by a Chatwood-Milner double bitted ten lever key-lock with rustless keys in duplicate. Various alternative locking arrangements can be supplied at additional cost if required, e.g. one or two combination locks in addition to the key lock, two combination locks or two key locks. Combination locks can be fitted with anti-observation shields and check locks. The boltwork is of improved design incorporating main and secondary locking.

Anti-Explosive and Re-locking Device
This is fitted to provide protection in the event of the normal locking control being disturbed by explosives and comes into operation automatically every time the safe is locked.

The safes are painted inside and outside with high quality smoke grey enamel. All furniture is heavily chromium plated. Locks, pull and bolt actuating handles are backed with a grey vinyl chloride polymer sheet as illustrated.
