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 Architec-
tural 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 drawing below for suggested bolt
sizes to use with your mailbox.
