Mailbox post is designed to fit over a section of 4X4 post. (included) If you have a current mailbox post that has a 4X4 post in already set in the ground this affords you the ability to cut the 4X4 post off 6" above grade and slide this post over, insert 4 screws and it is within the USPS specifications for Mailbox height. We are designing many posts with different themes and are open to new ideas on themes. This is just one of the themes available and custom posts can be ordered.
