No. The 4x4 post would be loose if it was not screwed to the post anchor. You should secure the post with screws and then unscrew them if you need to remove the post.

How tall is your fence? This item is 36" long and good for a 12' or taller post. You only need a 24" post anchor for a 10ft or shorter fence.

Can I use a 2 x 4 x 6 post with this? (even though there would be a gap in it)

The OZ Post was designed to fit a 4"x 4". It works very well when installed per design intent. Recommend upgrading lumber to 4 x 4

Yes, these will work for you they're fantastic only thing. I had to buy an additional item plus use a jack hammer to drive them in the ground. This item is mostly used for fence post hopefully this helps.

Functionally it is excellent. I rated 4 because of cost! Used to support retaining wall which was rotted out and inaccessible due to Neighbors fence so couldn’t use post hole digger.

PLEASE READ. WORTH the EDUCATION
1. Posts twist in clay/rocky soil so post are NOT square. I placed 172 posts the first time. See pic. This undermines entire structural integrity of uplift (the ONLY thing my engineers and town care about). 2. Top sways in wind. (Followed manufacturer recommendations for 36” oz for 4x4 posts 6’ apart for 8’ tall corrugated steel fence). Solution per engineer on site (towm made me hire one: cost $1,500 for design, another $?,??? for engineer inspection and approval). Had to add another 166 posts (none in the 6 corners of lot) at 4’ inside fence line (lost use of land and a pain in the butt to mow/maintain) with diagonal braces from this new stub to the top of middle rail...and added 2x5 boards to the top of each rail...which took FOREVER because every board had to be cut to fit the posts that were not square because of the twisting. Add up the lumber and time on that baby! Needless to say, my plan at this point is to finish the fence (almost there despite now being one year behind schedule because no one wants to put their name on a questionable fence due to legalities). So, I’ve lost a year of business. I’ve spent WAY more than expected and as much or more as a standard fence that would not have cost me my 4’ space around an entire acre. Looks bad. Not ideal. Is functional. Will be paying for new engineer plans and doing it the standard way. I was trying to be efficient and earth concious (less wood, no cement), and i paid the price in every way.

Posts were delivered as described. They are heavy duty and seem strong enough to act as a post footing. As others have described and any research will reveal, these are difficult to get into the ground....and thankfully so - if they are difficult going in, then they should be difficult to move once installed. At first I used a piece of 4x4 and a sledge to pound into the ground but again, as research will reveal, the 4x4 splinters and disintegrates. So I tried another 4x4 piece cut to the height of the post receptacle and pounded in with a 6x6 post section and it was much easier with success. The 3 foot long posts were more difficult to install for obvious reasons. Others have commented that it is difficult to keep the oz post going in plumb. It is. However, there is enough room once in and if installed close to plumb that your posts can be aligned plumb as well. I have installed 30 oz posts and the first 6 fence sections look straight as if a professional fence installer did the work. I expect the remaining sections to follow suit. It is too early to tell if the fence sections will hold up in high winds. I live in an area that rarely receives such winds. I would purchase these again.

dont buy these for a fence!
Im a contractor and tried my hand with these twice. The first fence I tried to use the ozpost for kept twisting and refused to stay level. There was alot of rock; but give me a yard that has zero rocks in the ground. The second fence was perfect ground conditions. The problem is that when youre driving the ozpost it moves ever so slightly to the left or right. I got the ozpost in straight( after twisting them back to my line) but that millimeter movement every inch of drivng put the ozpost away from where i needed it leaving gaps between my panels and post. This could work for a mailbox but not a fence with multiple post. Yes theyre strong but what good is strong if your line isnt lining up? Youve been warned.

Interesting product solution! I was looking for something that would give me the versatility of changing out a rotted post and prolonging the life of treated posts by keeping away from environmental contacts. This seemed to fit the need, a jackhammer installation is definitely the way to go though! I came across a jackhammer deal at Harbor Freight, and thought the jackhammer install kit would work but it didn't. The hammer I bought had a 1&1/8" shank, but the internals were different so I ended up with a daily rental at Home Depot of a jackhammer. Install was easy, I started off with a 3lb sledge to start the posts individually and get them in line before using the jackhammer. They zipped in with the 35lb jackhammer, and some twisted a little but I was able to straighten them out using a 24" pipe wrench to make slight adjustments to posts that were out of alignment. I also used a few composite shims here and there to help with posts that were out of plumb. Overall, a pretty good install, not sure if you save a lot of time due to slight modifications that you make to each post, but definitely saves your back from lugging around concrete everywhere! Really looking forward to see how this product holds up over time and future maintenance ease! I installed 47 of these, so the Jackhammer Kit was well worth $30. I also painted my posts holders black, to give them a better look for my fence project!

My old fence had rotted at the posts and was falling apart, I wish I had known about these when I had decided to put up the first post as an emergency procedure to hold up part of my fence (I used a concrete block instead). The hardest part is taking out the old concrete, other than that if you don't have concrete to take out from the old posts you're in really good shape. I replaced a 16 foot area, literally just went to Home Depot, got a 12lb sledge hammer, 2 - 8 foot length redwood pre-built wooden fences and 2 - 4x4 posts. Took about an hour after all the concrete was out to put up the fence (it was only me and my Dad). Make sure you have a post level (like 5$ bucks) and a measuring tape. I strapped on the level to the oz post got a cut out 2 foot piece of 4x4 post to go in the oz post and started pounding away. Stop every a few poundings to check the level and flex the post whatever way you need to get it back to leveled position. once the the base of the oz post reaches dirt level you're done. Just screw in 4x4 and repeat. My fence is pretty solid, if you want an almost unmovable fence make sure you custom build your wooden fence and add postmaster bars. Picture included shows new fence (left) old fence (right) sorry for the messy sealing job at the bottom had to use my fingers since the tube ripped open.
