Whitley Plastic, Crossarm, Convertible Mailbox Post, White

For a larger mailbox you need to use a larger post then 4x4. Needs to be for more support. Had to measure and cut a piecein lieu of buying 4x4 which I did and couldn't return. My mailbox is wood with cedar roof so weight is 14 pounds. Also to line up the screws and attach with the plastic piece there is barely room to get your hands in there to attach ! Easy no not really.....but looks nice..took 2 hours to do. But I was not experienced in this stuff so neighbor helped. Alot of work for me !

Pole was put together quickly, and when mounted was very sturdy. I really wanted a black post to go with my mailbox, however I improvised and spray painted it black. Looks awesome.

Easy to assemble and looks great.

It's a good buy for the money. It's really attractive and seems like it'll hold up well. Followed the directions to put in properly and it's easy as pie.

Looks great and installing was not difficult.... BUT... shakes in every direction because there is too much play between the 4x4 and the cover (not because the 4x4 isn't cemented correctly). You can see the gap at the base of the post (see pic). There is also play around the hole through which the mounting arm runs, and none of the screws fit tightly because the plastic is pliable, which may get worse with heat. Eventually, this will compromise structural integrity and shorten the life of the unit. I'm especially annoyed because shaking is what ruined my last mailbox (diff brand /design) and digging up 50 lbs of concrete is a pain. I'm going to try to remedy this with a 1/4" wedge between the 4x4 and the cover. Also, the kit requires a 48 inch 4x4, so be sure to have Home Depot cut your post in-store, or have means to cut it yourself if you can't purchase a 48 inch post separately. Would be great if kit included a stop-gap or instructions how-to.

This product was an excellent choice. It took me about a couple of hours last week to fully install. The install was fairly easy. When I installed the wooden post, I sprayed the 4x4 wooden post with WD-40. Then I picked up the two and banged in the 4x4 into the plastic post by lifting it up and dropped it against my concrete driveway several times until the wooden post was at the correct inside height. After that, normal post installation was a breeze. BTW, I used the Sika 33 fl. oz. Fence Post Mix instead of concrete. It worked easily and flawlessly. Nice & easy! It's available also at HD. After the complete install Crazy Glued the address numbers to the post, much easier that to try to bang in nails. Also, I made sure that I matched post with any Gibraltar post-mount mailbox with the designation letter codes A, B, or C. That's important. The only con were in the directions. I wish they were in a clearer step by step procedure. I found them to be a bit ambiguous and had to really study them to make sure each piece, especially the small ones, were inserted correctly. Here is an image of the completed project.

Great product easy to assemble! Took about 30 minutes to put together. Comes with mailbox base and hardware. Slips over 4x4 post. Does not come with letters and numbers. Overall priced right and home depot should make this an instock item. They would sell many more if it was...

This mail box post makes installing an attractive mail box easy. Just cement in a pressure treated 4X4 and slip this post over it. Some people complained that it wouldn't fit over a 4X4, but I had NO problem at all. It fit really nice.

This past weekend, I installed the Whitley PVC mailbox post, and I am really happy with my purchase. The 4x4 pressure-treated (PT) post I purchased fit perfectly with room to spare. If your PT post is still wet from the treatment it may be swelled and not easily fit… simply place your post outside to dry for a couple of days and it will shrink as all PT boards do over time. Someone complained about the post height to the bottom of the mailbox is only about 39-inches, but they forgot to add in the curb height, which is about 4-inches, and that brings the total height to 43-inches from the road surface, as the USPS specifies. Another person claimed the arm is not secure, but the package included a note and 2 extra C-size screws to secure the arm… you just have to drill your own holes in the sides of the post. I also caulked around the 2 end caps, and where the arm meets the vertical post. This will further secure it and keep out water and bugs. I used double-sided tape to affix my house numerals. The only thing that I wasn’t happy with is the mailbox stuck out too far and was about 2-inches in front of the vertical post. I had to do some customization by drilling 4 new holes for the mounting plate on the arm by moving the holes back 2-inches. Now the box sits right where I want it... with the back against the vertical post.
