What Customers Are Saying

Customers praise the post's heavy-duty steel construction with galvanized finish and powder coating, emphasizing durability in harsh weather and ability to support heavier mailboxes without bending. Most highlight straightforward assembly with pre-drilled mounting plates, completing installation in under an hour. The sleek black matte finish and modern design enhance curb appeal compared to traditional wooden posts. Some note the 4'4" height falls short of USPS requirements when set in concrete, and a few experienced alignment issues between sections or missing hardware. Overall, reviewers consider it a reliable, attractive upgrade that exceeds expectations.

Too short in length

Would Not Recommend

Because the length of this unit is 4'4" (52"), and the post office requires 45" from ground to bottom of mailbox, this is really too short, even with concrete. If they'd included a third segment, it would be perfect. the typical pre-made wooden versions are 72" long. Be ready to McGyver this.

Wrong Post

Would Not Recommend

It wobbles when you open and shut mailbox door where the pole locks together. Bottom section is secured in concrete. The top 1/2 is weak, I'm thinking of putting a rod of rebar inside the post and filling with concrete. If that doesn't work I'll need to find a better post to replace.

Less than sturdy.

Would Not Recommend

Very thin metal, threads broke off easily. Be prepared to redrill mail box and use JB weld to secure threads

Mail box support strength

Would Not Recommend

When the neighbors who replaced our broken mailbox pole, they told us the 22 gauge steel pipe pole was too weak to secure our mailbox. They replaced that pole with a 4x4 treated wooden mailbox pole. We ended up returning the pole and mailbox as inadequate to their purpose. The better choice, which we did not find at Lowe's, would have been a better choice.

Great Mailbox Post

Would Recommend

I like the way the post and the mounting plate for the mailbox are made. The post is made of thicker metal than I thought it would be. A great price.

Wrong choice

It wobbles when you open and shut mailbox door where the pole screws together. We added a screw add glue but still unsteady. Just to make sure you understand the pole is mounted in cement and that part is fine
