The AdirOffice dual key access office safe security system uses the same principle as your bank’s safe deposit boxes. You have a key, the bank has a key, and both are required to gain access. An advantage of this is there is no need to remember the combination or change the combination if an employee leaves the firm. It also eliminates the possibility of an intruder fiddling with the dial in an attempt to gain access. For home or business the AdirOffice 670-900-01 safe offers peace of mind when it comes to securing valuables. Class B safe rating.
