Stack-on safes are light enough they can be carried off and opened at the thief's leisure. Yes they are designed to be bolted to the wall, but do you know anyone that actually does that? Even if they do, it's not that hard to rip one off the wall. All it takes to open one is a good cold chisel and a hack saw, an air operated chisel, or a hand held grinder. All tools I have in my garage, as does many people.
We own three vaults. One for my son, a 600 pounder. One for the wife, hers is 800 pounds. And mine is 1200 pounds. All three are anchored to the concrete floor, and bolted to the wall with 10 " 5/16th lag screws. All are fire rated
My neighbor had a 800 pounder sitting in his den, on the second floor. He did not want to bolt it to the wall, since it would screw up the sheet rock. Said it was too heavy for a thief to move anyway. One day his new bride and I was talking in the den and I told her I could get the vault out of their den and on the ground outside in less than five minutes. She wanted to see how I would do it.
I took her outside and pulled the winch cable out of my windh on the Jeep. I threw it through the open front window. I then simulated kicking in the front door. Going up stairs, I wrapped it around the vault. Getting the cable behind the vault was no problem since it was not bolted to the wall. Then I showed her how all I had to do was drive the Jeep backwards, The momentum of an 800 pound vault would smash it right through the exterior wall and onto the ground outside. Then using a couple of boards and my Jeep I could drag it up and into the back of a pick-up. Off we go to find a garage to work in and open it at our leisure. Yes some of the scopes would be damaged, and some of the guns might be scratched up a lot, but on the Black Market 10 cents to the dollar, who cares.
The following week it took seven of us to get that vault down into his basement. I drilled the holes through the carpet and into the concrete to anchor it down. Now his new bride is happy.
