VERIFIED PROTECTION RATINGS:



RSC burglary rating plus 60-minute ETL fire protection
Built for homeowners protecting valuables, firearms, and documents in one tall cabinet, the AMSEC BFS4520 from the BFS series pairs a UL-listed RSC Level 1 burglary classification with ETL-verified fire protection tested for 60 minutes at 1200 degrees Fahrenheit. A 1/2-inch solid steel plate door and 2.31-inch double-wall body anchor the construction. This model is imported.
This is the largest model in the BFS lineup, standing 49.875 inches high by 25.125 inches wide by 25.75 inches deep and weighing 900 pounds. The interior measures 45.25 inches tall with three adjustable steel shelves, giving a tall, deep cavity for long guns, binders, and bulky valuables behind a 900-pound body that resists removal.
Engineering & Security
- UL-listed RSC Level 1: Carries a UL Residential Security Container classification, verifying resistance to common hand-tool pry and prying attacks.
- 1/2-inch solid steel plate door: The door is a solid half-inch steel plate with an overall door thickness of 1-1/2 inches for added rigidity against attack.
- 2.31-inch double-wall body: Double-wall steel construction encases the fire-resistant fill, combining burglary resistance with the rated fire barrier in one shell.
- Ten four-way active bolts: Ten 4-way active locking bolts engage the door frame on multiple sides to resist forced entry.
- Four hinge-side deadbolts: Fixed deadbolts on the hinge side keep the door anchored even if the external hinges are cut.
- Spring-loaded re-locker: A spring-loaded re-locker secures the boltwork if the lock is punched or attacked, backing up the ESL10XL electronic lock.
Fire Protection & Interior
- 60-minute ETL fire rating: ETL-verified by Intertek for 60 minutes at an exterior furnace temperature of 1200 degrees Fahrenheit to shield contents.
- Fire-resistant fill: Proprietary fire-resistant material between the double walls forms the insulating barrier behind the rated door.
- Three adjustable steel shelves: Three adjustable steel shelves organize documents, valuables, and gear within the 45.25-inch-tall interior.
- ESL10XL electronic lock: The Type 1 ESL10XL digital lock allows one user and quick programmable 6-digit code changes for daily access.
- One anchor hole with hardware: Includes a pre-drilled anchor hole and hardware to bolt the 900-pound safe to the floor.
Ideal Buyer & Use Cases
The BFS4520 suits a homeowner who wants combined burglary and fire protection in a single tall cabinet, measuring 49.875 inches high by 25.125 inches wide by 25.75 inches deep and weighing 900 pounds. Its UL RSC rating and 60-minute ETL fire rating cover both everyday theft risk and house-fire exposure.
As the largest model in the BFS series, it steps up from mid-size options like the BFS3416E1 and BFS2815E1; buyers needing a smaller footprint can consider the compact BFS1512E1 or the entry BFS912E5LP.
