The Secret Safe 115, 180, 240 and 265 series can be compared across different sizes and design options. Users who need a stronger, wall/floor-mountable safe can also check the Mounted Steel Safes category, while businesses that need key storage can check the Key Cabinets category.
When choosing a hidden safe, the product's camouflage type, outer dimensions, interior volume and the size of the items to be stored are important. These products are not an alternative to high-capacity steel safes; they are a solution for storing small valuables in a discreet, more controlled-access space.
No. Hidden safes are suitable for camouflaging small items. If higher physical security, mounting and larger capacity are required, a steel safe should be preferred.
It can be used in homes, offices, stores, study rooms and shelved spaces to keep small valuables out of sight.
The largest dimension of the item to be stored should be the basis for selection. If a passport, documents or multiple small items will be stored, choosing a model with a larger interior volume is more practical.
