Constructed from heavy-gauge galvanized steel and finished with a durable powder coating, this 43-inch post is designed to withstand outdoor conditions while maintaining a clean, professional look at the curb or entryway.

Key Benefits

• Heavy-duty construction using 10- and 14-gauge electrogalvanized steel for lasting strength.

Material & Durability

The in-ground post uses heavy-gauge steel elements to resist bending and wear. Electrogalvanized construction paired with a protective powder coat offers robust corrosion protection, helping the post maintain its appearance even in damp or coastal environments.

Installation & Use Scenarios

Designed for outdoor spaces where a sturdy mailbox base matters, this post can be mounted by sliding over a wooden 4x4 post for a deep in-ground setup. For added rigidity in challenging soil or windy locations, reinforcement with rebar is a practical option.
