Fort Knox has a dealer locater on their page. They are class acts. Give them a call. You will be surprised how easy they are to deal with. I haven't outgrown mine but a lot of other valubles seem to find their way in there. The only thing I didn't get that I wish I did was the lighting package that comes on when you open the door. I love the electronic lock. I can have that door open in 5 seconds if I want to.
