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.
