Speaking from personal experience, not bolting down your safe is asking for trouble. When I moved my safe into the Garage, I thought this thing is so heavy, its never going anyplace. And until I decided exactly where I wanted it, I moved it a few times, so bolting it down would have been a hassle. But all that went right out the window the morning of the Northridge Earthquake. That 1200# chunk of steel fell over on my car. It took hours of jacking and blocking just to get it off the car. At one point I had a Bottle Jack, applying pressure across the fender, using the smashed fender and tire to apply pressure to the Safe's Handle with 2X4's. Of course everything in the safe was against the door,and the car had moved during the earthquake so it was at some point up against the safe before the safe fell over. I realize that some of you do not live in Earth Quake Country, but I have also seen a safe fall over from the weight of the door, and all the stuff the guy had hanging on it...One Hand Gun To Many....
