The AM4020 safe offers top-tier protection for your firearms and valuables. Featuring a 1/4″ solid steel plate door and a 12GA steel body, this safe is designed to withstand intense pry and sledgehammer attacks.
Locking protection reaches three sides
Three-way boltwork engages multiple edges of the door, making it harder to gain leverage by attacking one side.
Fire protection is built into the shell
Fire-protection panels work with the surrounding steel to slow heat transfer and help protect contents from fire and smoke.
Ready for powered accessories
An electrical access opening makes it possible to add lighting, humidity control, or other powered accessories without routing a cable through the door.
Designed to stay where it is installed
Four pre-cut anchor points allow the safe to be secured against tipping or a carry-away theft attempt.
