The Nighthawk Mobile Vault is a pistol safe designed to hold one pistol/handgun, small documents, wallets, or jewelry. The safe opens like a clamshell (top flips backwards), so you can easily access your stored items. There is a security cable that mounts to the left side of the unit to easily attach it to a secure surface. There are also two predrilled holes on the bottom for additional mounting options. The Mobile Vault is ideal for placement next to a bedside, in a closet, or dresser, under a desk, or in a garage, cabin, car, or more! Easily transportable and securable, you can take the Nighthawk Mobile Vault with you wherever you roam. The Nighthawk II features a key lock. This lock operates with one unique key, and does not use any batteries, so you never have to worry about changing them out. Perfect for securing a pistol or storing a wallet, small purse, cash, jewelry, ammunition, or prescription drugs, the Nighthawk Mobile Vault II is also great for storing small, important documents such as passports, etc.
