ABSTRACT:
A double-door security rural mailbox having oppositely faced front and rear closures permitting safe, easy access thereto by the rural mail carrier and the owner of the mailbox. The mailbox has a locking mechanism including a key operated lock for locking the rear closure. The front closure is provided with a locking mechanism which allows the front closure to be freely opened and closed once by the mail carrier before securing in a locked position. Thereafter, the front closure may only be unlocked by unlocking and opening the rear closure. Once the rear closure is again closed and locked, the front closure may again be opened and closed once by the mail carrier before securing in a locked position.
