Elevate curb appeal with a durable, weather-ready mailbox post

The Mayne Newport Plus Mailbox Post with Standard Arm blends a classic silhouette with modern materials. The decorative sleeve and reinforced arm provide a sturdy mounting platform for everyday mail delivery while enhancing your home's exterior.

Key materials and finish

Made from UV fade resistant polyethylene, the post holds its color through sun, rain, and seasonal shifts. The fade resistant surface minimizes maintenance while preserving a premium look over time.

• Weather-ready construction withstands sun, wind, and moisture
• Fade resistant finish helps keep the color vibrant year after year

Compatibility and load capacity

The Newport Plus arm is designed for added weight, supporting mailboxes up to 8 lbs and fitting a standard 4x4 post (sleeve measures 3.5x3.5).

• Fits standard 4x4 wooden posts for easy upgrades
• Supports moderate mailbox weight for reliable daily use

What is included and what is not

Package ships in two boxes: decorative post, mailbox arm, and a hardware pack to install the arm. A 4x4 post, mailbox, and mailbox mount are not included.

Installation and durability

For best results, bury the post about 2 to 3 ft in the ground and leave about 4 ft above ground. Slide the decorative sleeve over the post, attach the arm, and mount your mailbox using a compatible plate or bracket (not included).

Made in the USA with peace of mind

Mayne backs the Newport Plus with a 15-year limited residential warranty, reflecting a commitment to durable, dependable performance across seasons.
