ABSTRACT:
A mailbox bracket assembly (400) for attachment to an existing mailbox door (105) operates to provide a signal when the mailbox door (105) has been opened. The mailbox assembly (400) includes a signal holder arm (101) perpendicularly mounted from the face of a mailbox door (105). A ring section is used for holding a signal ball connected to the signal holder arm while a guard section may be used for blocking objects from inadvertently contacting the signal ball. The signal holder arm (101) extends from the mailbox body such that the position of the signal ball can be easily observed from the rear of the mailbox.
