Installing a Safe

[ELB]

"If the door on a safe can be pried open...it isn't a safe...it is a security container. "

Well, not exactly. Safes are not burglar proof, only burglar resistant. The most common UL ratings for burglary resistance are TL-15 and TL-30, which means the safe will offer "limited" or "moderate" resistance to opened with common hand tools for 15 or 30 minutes, respectively. There are many safes that do not even achieve these ratings, particularly fire safes. Lower cost "gun safes" often only offer either fire resistance, or tamper resistance.

I'd still bolt it down, for the safety factor if nothing else, and if you have a gun safe of any kind, you are still way ahead of a lot of people. It will deter fast moving burglars looking for easy scores. Someone who really wants your guns will bring the tools and manpower to do it.

I'm gonna throw my two cents in a few days late here. I've got a friend who owns a locksmithing company, and I've learned a little helping him out from time to time. It's surprisingly easy to move even very heavy safes if they are unsecured. 2 reasonably strong people with a pallet jack can easily lift and move an unsecured safe-in fact, on a concrete floor, a single person can roll a 4000 lb safe on a pallet jack.
Also, you would not believe the different ways of opening a safe. The most common method I saw was pretty unsophisticated. They just took any number of different power tools to the safe. Unless there is a remote monitoring system(that they cannot find and disable), they will generally have more than enough time to open even a commercial anti-burglery safe.
It's scary what a determined person with a 20lb sledge and an angle grinder can do in 20 minutes.

Guess we shouldn't keep black powder in the safe, then: those guys could get hurt.
