Hardware
Mailbox mounting hardware is included with all new Architectural
Mailboxes posts and 4x4 wood-post adapters. If you are using an
existing post, not made by Architectural Mailboxes, please reference
the mounting hole diameter and pattern in Option 2 to determine
the hardware you will need for installation.
CUSTOMERS ARE REQUIRED TO CONTACT THE LOCAL
POST OFFICE BEFORE INSTALLING THE MAILBOX TO
ENSURE ITS CORRECT PLACEMENT AND HEIGHT AT
THE STREET. GENERALLY, MAILBOXES ARE INSTALLED
AT A HEIGHT OF 41–45 INCHES FROM THE ROAD
SURFACE TO EITHER THE INSIDE SURFACE OF THE
MAILBOX THAT THE MAIL IS PLACED ON BY THE
CARRIER OR TO THE LOWEST EDGE OF MAIL ENTRY
(FOR LOCKED MAIL SLOT DESIGNS) AND ARE SET
BACK 6–8 INCHES FROM THE FRONT FACE OF CURB
OR ROAD EDGE TO THE MAILBOX DOOR.
Keys
Your new mailbox comes with four keys. The keys allow access to the storage compartment. To retrieve
incoming deliveries, simply open the access door at the bottom of the box. IT IS IMPORTANT TO
NOTE THAT IT IS NOT THE RESPONSIBILITY OF MAIL CARRIERS TO OPEN MAILBOXES
THAT ARE LOCKED, ACCEPT KEYS FOR THIS PURPOSE, OR LOCK MAILBOXES AFTER
DELIVERY OF THE MAIL.

One Phillips Screwdriver
Option 1
For use with compatible
Architectural Mailboxes
posts and adapters...
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.
Option 2
For use with non-Architectural Mailboxes posts...
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.
