Im looking for information on a safe that I am considering buying. It is probably 15 years old. It came out of a jewelry store that closed. It is a TL-15 Tool resistant safe weighing approximately 3400 lb. (72 in tall) (40 in wide) (30 in deep). It looks like at least 1/2 in plate all the way around. I guess the brand was scrubbed off at some point. The TL-15 burglary certification is the only tag on it. Thanks for any help.
