The stabilizer system exclusive to Yankee Mailbox makes the strongest mailbox post design by fastening the mailbox to both the brace and vertical post. With the stabilizer system Yankee mailbox posts can hold strong to the weight of the snow that hammers the side of the mailbox from plows. The stabilizer block also has a nifty flag slot to hold Old Glory. All mailbox customers receive a complimentary American Flag and stabilizer system.
