ABSTRACT:
A simplified attachment for a mailbox which alerts the mailbox addressee that mail has been delivered. The attachment includes a signal flag mounted on a spring activated spool rotatably secured within a housing affixed to the side of the mailbox. When the mailbox door is closed, the upper end of the signal flag is held under tension in a horizontal position by a keeper mounted on the door of the mailbox. When the mailbox door is opened, the signal flag is released from its horizontal position and, powered by the spring, rises to a vertical position above the mailbox to alert the addressee that the mail has arrived.
