I'm sorry if I can not give you the exact combination and I'm sure no one does. Because that is what Sentry Fire-Safe is all about, secrecy.
However, the best solution for your problem.... to be able to acquire the right combination for your safe.... is to call the attention of Sentry Safe Shop
You must call (800) 828-1438 for combination retrievals.
or send a notarized letter stating you are the owner of the safe, personal information, model and serial number of your safe and must indicate the method on how you will receive the combination.
