Rated 4.4 out of 5 by 20 reviewers.
Rated 2 out of 5 by Too short The post is well made and looks good, but is too short. According to the USPS website "mailboxes should be installed at a height of 41-45 inches from the road surface to the bottom of the mailbox." With the post being 46.5", at a height of 41" only 5.5" are left for anchoring. At 45" above ground a ridiculous 1.5" is left. I cheated and put my box at 38", giving me a whopping 8.5" in hte ground. The hole is 15" wide and filled with concrete and there is rebar going up into the pole, I also drllled holes in the post to put two 12" pieces of rebar into it horizontally. It still wobbles. Not worth the price. I would not buy again, nor can I recommend it to others. September 6, 2011
Rated 5 out of 5 by A MUST HAVE for your mailbox This post is required if you want your mailbox to be free standing and not enclosed in concrete or stone. I needed a mailbox with a lock (Architectural Mailboxes Oasis Post Mount Mailbox) and found one for $98 at Home Depot. The box did not specify clearly you need to purchase a post. The box showed one picture with the mailbox on a post and another with it encased in stone. I did not see the posts at the store so I ordered it online. Fortunately, it did ship quickly. The post is very heavy and durable. Once it got cemented in from the bottom, the post was solid and the mailbox was very sturdy, barely moves. Overall great product, both mailbox and post.

Rated 5 out of 5 by Mailbox Post - Black The product is fabulous with one exception, Home Depot does not offer posts in all the colors available from the manufacturer. For example, no grey. Also the cardboard box containing the post was way too weak for the gentle hands of UPS. The post is very sturdy, well designed and very much up to the rigors of drivers and the weather. I highly recommend the product. H July 10, 2010
Rated 4 out of 5 by Nice Post! Functional, as advertised post. Only drawback was the mounting plate not level to the post, but close enough to work - reason for 4 stars. September 13, 2011
