Surface Mount Plate

The Surface Mounting Plate creates a wider, steadier footprint for your mailbox setup, reducing sway and keeping your mailbox level over time. It fastens your Adoorn mailbox to the top of any existing 4×4 wood or metal post. This is the same plate that ships standard with our In-Ground Post, sold here on its own for setups that already have a post in place. Compatible with all Adoorn post mount mailboxes and most other mailboxes with a standard 10″ × 4″ hole pattern.
