Large sized safe for offices, home, and commercial use



Single Door Large Standard Safe is a popular choice for consumers searching for single-door large safes with plenty of storage capacity. The BWB4020 Safe is suitable for storing vital documents, items, and cash in offices and organizations. Household use is also prevalent. The AMSEC BWB4020 Large Safe is 40 inches high, 20 inches wide, and 20 inches deep. BWB is an abbreviation for B rated and Wide Body. The numbers represent the front exterior dimensions, which users can use to determine where these safes can be mounted.

B-rated burglary classification



Safe has a B fire rating. The recessed ½” thick steel door prohibits any intruder from opening it. Internal jambs on all four sides of the BWB series safes are composed of high tensile strength steel and protect the contents from sledgehammer strikes. The bolts total five in three directions and are composed of enormous 1″ solid steel material with a chrome finish.

Detent system with auxiliary relocker 


B-Rated Safe also has a detent system for its bolts, which keeps them retracted until the door is closed, at which point they engage automatically. If the hard plate door is drilled through, the safe incorporates a spring-loaded auxiliary relocker mechanism that engages and improves the safe’s security by locking the bolts in a closed position.

U.L. approved dial combination lock


B-Rated Safe has a changeable combination lock of Group II type that is listed by Underwriters Laboratory (U.L). This safe includes four anchor bolts at the bottom and three adjustable shelves, which is the maximum for this product series.


Security Safe is manufactured by American Security, a known name for safes and vaults since 1946, which means the goods have been time tested and are assured to be of high quality.

The fundamental question is why safety is vital and what you could benefit from it

The major reasons are to keep your private documents and assets safe, as well as to protect not only yourself, but your family and others, through harmful materials out of the hands of unskilled people.
