GunVault is pleased to introduce NanoVault 300, the compact, secure and affordable handgun storage safe solution. The next evolution in the NanoVault line, this safe features an easy to operate combination lock system and is perfect for home, travel or concealed weapon permit holders. The NanoVault 300 meets TSA airline firearm guidelines and fits discreetly in a bag, briefcase, desk or under a vehicle seat. The NanoVault 300 features 21 gauge steel construction and 1.25 inch thick memory foam interior. Each unit comes standard with a 1,500 pound test security cable. When the cable is wrapped around any fixed object and slid over the lock receiver inside the security box, both the NanoVault and any valuables will be securely attached.
