Chubb Fortress Size 1 – High-Security Burglary & Fire Safe
The Chubb Fortress Size 1 is the most compact model in the Fortress series, specifically engineered to provide maximum dual protection for cash, jewelry, and important documents. Despite its smaller footprint, it maintains the same heavy-duty, unyielding build quality to resist sophisticated burglary attempts and extreme fire temperatures.
Key Features & Construction
-
CENTRIX I Barrier Material: The safe body has an overall thickness of 90mm, consisting of inner and outer steel plates enclosing a seamless, monolithic casting of Chubbsafes' specially formulated CENTRIX I barrier material for high resistance against physical attacks.
-
Reinforced Door: The 138mm thick door (with a 30mm effective thickness) is filled with CENTRIX I steel-fiber barrier material. The back of the door is further protected by a steel pan filled with additional fire-resistant material.
-
Robust Locking System: The door is secured by a heavy-duty 3-way moving steel boltwork system (32mm diameter bolts) and a full-length docking bolt on the back edge of the door. The vital locking areas are fortified by drill-resistant manganese hard plates.
-
Dual-Lock Security System: Combines a high-security German-made 8-lever key lock with a 3-wheel manual combination dial lock. This mechanism is protected by an active Glass Relocker that permanently deadlocks the system if a forced entry attempt using drills or explosives is detected.
