Safe Ratings - How to tell the difference.
B
B-Classification / Good Protection
The “B” burglary resistive classification is an industry construction and performance rating. This type of construction rating was established by the insurance industry to develop a standard that will indicate the degree of protection a safe will provide against an attempted burglary attack.
Construction Specifications
Steel doors less than 1″ thick and steel body less than 1/2″ thick.
C
C-Classification / Better Protection
The “C” burglary resistive classification is an industry construction and performance rating. This type of construction rating was established by the insurance industry to develop a standard that will indicate the degree of protection a safe will provide against an attempted burglary attack.
Construction Specifications
Steel doors at least 1″ thick and steel body at least 1/2″ thick.
