Of course!!!!I'm assuming you have holes in the floor of the safe to run all thread into the concrete.
The safe in question in the video was probably cheaply made. Or or poorly designed.
Well the safe is back from powder coat and looks great. I am building custom sorting rods to hold up the Guns in the safe. That way I can place the guns wherever I want. The rods are 10/32 bronze all thread with a magnet on one end. The rods will all be 18" long. With the rods I should be able to store A LOT of guns and ammo in this safe. Very happy with the end result. I will not be fire lining it figure 1/4" plate will be more than enough. Now I need to get this beast into my garage lol. I have a lift gate on one of my trucks and a pallet jack. A local safe company said they would move it for $330 which I am really considering.
