Our double mailbox mounting bracket is an accessory for our 6" X 6" square post to allow 2 mailboxes to be mounted side by side on the same post.
There is about 3" left between the mailboxes when installed so laser cut numbers on the sides will not be as visible. A mailbox mounted address plate (available in our shop) with a Quick-Ship mailbox (no numbers) is an alternative option for the mailboxes being double mounted.
Note: POST AND MAILBOXES SOLD SEPARATELY
