Re: DIY ~ a step-by-step on how to install your safe (
how would anyone not know how to drill a hole into a wall to secure something to it? ...
anyway - because we recently also had to install a safe:
i would recommend a safe that not only has holes on the bottom, but also on two sides. in the presented safe, with the door opening to the right, you would want
* to have the holes at the back and on the left-hand side.
* move the safe to the left corner of the room. bolt it at the bottom, left and back of the safe.
(this is assuming that you have a proper floor as well as wall: concrete in the cellar is usually ideal.)
regardless of the side which you try to apply force from, there will be a bolts from the other two sides holding against it.
for your presented safe, eating away on the wall at the back of the safe would allow to put a sling around the top of the safe - then the safe itself would work as a lever against the bolts on the bottom (because there are no bolts holding the safe to the back) -> adding bolts to back, it would already be significantly more stable.
also - mounted in the corner gives less access to the safe. in your case, 4 sides are accessable. in the corner, it would be three.
just my thoughts.
