ABSTRACT:
A mail delivery indicating device which attaches to the side of a standard rural mailbox and drops a signal flag when the front cover is opened upon mail delivery. The device is especially designed for ease of assembly, installation and operation having only three (3) separate parts, a base with support arm and flag, a metal clip for the front door and a screw for attaching the device to a mailbox. The device is simply installed by inserting the one (1) screw in the pre-drilled hole in the mailbox, sliding the clip on the front door and closing the cover upon the trip lever of the device. When the cover is opened, the trip lever is released, thereby allowing the flag to drop downward so the homeowner can see whether mail has been delivered without having to leave the house. An additional feature includes a flag portion on the end of the signal arm which consists of two (2) perpendicular flags so the device may be seen from all directions.
