READ ALL INSTRUCTIONS PRIOR 
TO ASSEMBLY AND INSTALLATION.
Important Note: 
Customers are required to contact their local 
post office before installing the mailbox to 
ensure its correct placement and height at the 
street. As a general rule, most mailboxes are 
installed at a height of 41" to 45" from the top of 
the street surface to the bottom of the mailbox 
and 8" set back from front edge of curb. These 
measurements can vary per your local postal 
requirements, so check with your local post office 
before installation. (see Diagram A)
Assembly: 
Attach scroll support brace to round pole using 2 
bolts provided. Attach mailbox to top of support 
brace using either 4 or 5 bolts as provided. If 
you ordered the standard economy mailbox, the 
support brace attaches to the wood platform 
under the mailbox with the 4 large wood screws 
provided. Snug bolts firmly, but do not over-tighten 
them. If a finial (or solar light) is not attached to 
the round pole, slide it over the top of the pole 
and snug set screws against the pole with an 
Allen wrench. Slide the decorative base onto the 
bottom of the round pole, but keep it low on the 
pole and do not tighten yet. Get a measuring 
tape and measure the distance from the bottom 
of the mailbox to the bottom of the decorative 
base. Gently slide the base up the pole (without 
scratching the pole) until you have the correct 
measurement for your local USPS code 
requirement. This measurement will typically be 
between 36" to 42", which will leave around 12" to 
16" of round pole extending below the decorative 
base. This extension is what you will put into the 
hole and pour concrete around. Once you have 
the correct decorative base adjustment, snug the 
Allen set screw(s) at the top of the base so the 
base will not slide up or down.
Installation: 
Dig a hole approximately 16" deep (this will vary 
due to local postal codes) with post hole digger 
or small shovel. Install completely assembled 
post into hole and check for fit. Mix quick set 
style concrete and pack it in around the post in 
the hole. Place a spirit level on the round pole 
and level the mailbox post front to back and 
side to side. Some temporary supports may be 
necessary until the concrete dries.
