Question: Do you need to add a 2x4 to two sides for a snug fit?
Document: Once you own a this deluxe post, you need to replace it with the same one. It look great if properly installed. To install it properly, you need to add 2 x 4's to two sides of you 4 x 4 post. This was a replacement for the one we installed 12 years ago. The original was in okay shape, someone broke the cross arm off in January.
I have owned two of these mailbox posts. The first one installed very easily. Mine came with instructions to add a 2x4 to adjacent sides of the 4x4 post so it fits the plastic post sleeve perfectly. Unfortunately the first one was demolished by a snow plow. In MN that happens often! :-)  I happily bought another and slipped it over the wood post which survived the snow plow undamaged.
I like the post, but the dimensions leave a lot of room for movement over a 4 x 4 post. I had to shim it in several places. I would have liked it to slide over with more of a snug fit.
Otherwise, this is an elegant looking post for a great price. Once your post is cemented in, it is VERY easy to replace should you need to do that some day.
I'm pretty sure I have the prettiest mailbox in the neighborhood now! Ignore the directions to nail together two boards to build your own 6x6 post--Lowe's already has 6x6 posts (they're conveniently located next to their mailboxes and posts). The post is plastic, but it's sturdy once you get it mounted on the wood post.
This mailbox post is really nice. It was easy to assemble and place over the wooden post that must be installed before you can set up the actual mailbox post. All the required hardware was present and fit well. I would recommend this mail post to a friend. Looks nice and goes well with our house design.
Previous mailbox and post destroyed by Tornado in '07. ..... Bought this to replace in 2007. Instructions were defective, so tried to install only on treated 4x4. Every bad sag, etc. mentioned in negative reviews happened. and looked terrible -- even to me, the installer!. .... Finally, used 2x4 shims, as now recommended. WOW! Everyone isn this upscale neighborhood complements "this" mailbox.
I needed an attractive and easy to install post, as I had to get one up quickly. Our neighborhood has mostly brick mailboxes, so needed one substantial and nice enough to fit in. This one had a very nice style. We had an existing 4x4 wood post to cut to the recommended height. I am very disappointed with how flimsy it is.
If you need to get something up fast, use a 4x4 stake with a 4x4 post sold at your local home improvement store. It will actually last long enough to get something up that's more substantial, and look decent while doing it.I would have given this thing a negative rating if I could...it's that bad. Unequivocally not recommended.
This was purchased to replace an identical post bought over 10 years ago at Home Depot. My daughter slid into the post with the side of the car trying to enter our icy driveway on a very frigid evening, and &#34;crack&#34; - the 10 yr old post shattered. This was an exact replacement and fit perfectly. Mailing time was speedy and the product was exactly as promised and in perfect condition.
