Capacity
The volume of the interior space of the safe. Usually this parameter is indicated taking into account the safe-in-safe and other additional internal compartments. The amount of content that can be placed inside directly depends on the volume; on the other hand, it affects the external dimensions and weight of the storage.
Number of shelves
The number of individual shelves provided in the design of the safe (if any). These structural elements make it easier to store small items: it is easier to lay out the "trifle" on separate shelves than to lay it in a continuous pile on the floor of the safe. On the other hand, shelves divide the overall volume of the safe into parts and can create difficulties for large items. Therefore, in gun safes (see "Product Type"), the shelves occupy only a part of the internal space, which is separated from the rest of the volume by a vertical partition.
Some safes provide the possibility of rearranging the shelves to different levels — similar to how it is implemented in refrigerators.
The minimum design of the safe provides
1 or
2 shelves, and in more advanced models their number can reach
3 or
more.
Safe in safe
The availability of an additional compartment located behind the outer door and locked with its own lock. The term
"safe in safe" is used for all types of storage, except for guns — there we are talking about the ammo compartment (see above). Anyway, such a cell provides additional protection for the content placed in it, but the features of this protection may differ depending on the model. So, the simplest safe-in-safe protect the contents primarily from prying eyes, and their burglary resistance is not much higher than the specs of a lockers in a supermarket. There are also safes with reinforced locked boxes that can create serious problems even for a well-equipped burglar.
