Jim:
A vault door may not be necessary unless you really need a blast door
or you are very worried about theft. If you are far enough from a likely
ground zero
and able to at least somewhat hide your door, a steel fire door will probably
suffice nicely. For bargains, look for commercial demolitions, or contact
people or companies who do this. Tell them you are looking for a swinging conventional
doorway sized steel fire door, preferably with the steel frame, dent and
scratch
is fine. If you must buy new, find a 90 minute rated steel fire door. They
have cheaper ones for residential use--commercial is always at a premium.
Consistent with the recommendations for safe room doors, you want minimum six
points of
attachment from door to frame. The best way to do this is three strong hinges
with really heavy and deep screws on one side, and three deadbolts on the other
side. You should space your deadbolts top, center, and bottom of the door
handle
side. To really be secure, add two more, top center and bottom center of
the door. Go to a lock store or home hardware suppliers and get all deadbolts
keyed
the same. That can provide good security and protection at a more reasonable
price. For combination entry, there are combination deadbolt locks also.
For EMP concerns I would stay away from electronic ones. Those little key boxes
that real estate agents use are nice, and can be hidden easily so you are
never
without a key. http://www.nokey.com/comlocbox.html Rourke
