Option 1
Option 2
Align the mailbox mounting holes
with the holes in the mounting plate.
Attach the mailbox to the mounting
plate using the hardware included
with the Architectural Mailboxes
post or adapter.
Identify if your existing post or mounting surface has a matching
hole pattern with the mailbox. If there are no matching hole
patterns, you will need an adapter plate or piece of wood to drill
the mounting holes into. Architectural Mailboxes does not
recommend drilling new holes in the mailbox, as that will expose
untreated metal and void the product warranty. Use the drawings
below for suggested bolt sizes to use with your mailbox.
