Sturdy post

from Tampa, FL – Verified Buyer

We purchased this to match the mailbox. It set up in the ground with some quick-concrete easily. The mailbox mounted on the post with great ease as well. The mailbox and post aren't going anywhere! We love it and the compliments that we get.

Sturdy and simple

from Salem, OR – Verified Buyer

This post (got the in-ground model) seems very stout, is powder coated to match the mailbox, and fits the bolt pattern perfectly. Glad we bought it.

Great Accessory

from CA – Verified Buyer– Top 100 Reviewer

It would be even greater if I had picked the right type of post. I should have gotten the surface mount so that it can go onto concrete.
