The Study "safe" is a big step up from most RSCs. Number one is simply the amount of steel used. Number two is the bolts are long and boxed in on the door with steel making them a great deal more resistant to being able to be pried open (Pivot around). The edge that the bolts are held by is also a great deal stronger than on the cheap RSCs. The steel has more folds along those edges the bolts are held by and there is some sort of hard material in between the folds as well. You won't push a Sturdy over and pry the door open like they do with cheap RCS on Utube.
I "drew" a pic in Excel. I forgot the hinges, but they are on the left side.
