I would truly like to know how you plan on getting the Fort Knox down in to the basement of your home as was asked earlier?
Secondly, being a retired police detective, I vividly recall a burn bar being used to open a safe very similar to what you refer, and at least a $100,000.00in jewelry as well as several high dollar shotguns and rifles.
I realize that, the burglary to which I described was done by professionals, that had an opportunity to observe the vault in person, and also new of the alarm system set up in the home. Incidentally, they were friends (so to speak) of the victim and were apprehended.
I, myself prefer the Cannon brand of gun vault, as I currently own 2, had one burglary in the past 20 years, and needless to say all my firearms remained in tact. Only a few small replaceable items were taken.
Another thing, on the Cannon brand, if they do succeed in getting into the safe and removing the items, Cannon will replace those items, and will repair the safe, free of parts, and labor for as long as you own the safe.
No I don't have any financial interest into Cannon, but I do know they have been involved in the gun safe business since 1963 or so.
