Customer Questions & Answers

Would this support a 6x6 for a 5 ft wide, 6 ft tall gate, framed with four 2x4s, one 2x4 diagonal cross support, and 11 pickets?

Asked by: sladeltd
I set ours in concrete and about 2 inches of drainage stone above that. Our gate is about 4 feet. I wasn't concerned about the oz-post moving at all; however, wood posts themselves will warp over years. To address that I built an arch between two posts from the same wood, but inserted metal bars in it.

Do you still use cement?

Asked by: Smithd
I did. I didn't have the right tools to hammer through a layer of dense clay. The 6x6s would probably stay straight if I had a rig to brace them while using a jackhammer; however, I didn't want to risk any twisting on critical parts of the fence. I tried using a sledge hammer and OZ-Post tool to place the 4x4s, but the soil in that area was filled with roots and rocks and they started twisting. So there again, dug them out and placed in concrete. I suppose a selling point is that the oz-posts make for faster build; however, I bought them to get the wood out of the soil to avoid rot and to make it easy to replace posts if they do warp over time.

Can it be used to hold a pergola 12x12 corner posts using 6x6

Asked by: Guisito
I used this for the 4x4 version and it worked great for my 12 x12 pergola. I built it on top of an old ficus tree that I had grinded down, so it worked great getting through the roots. It's not going anywhere :)

Will this work well in sand and clay?

Asked by: Giselle
Sand? I doubt it. Clay? Probably, if it is like the clay in our area. The problem I had with ours is that it was so dense, hard that I couldn't keep the posts straight while pounding through it. I ended up just digging it out and putting in concrete. For me, it wasn't about speed, but that I could get the posts off the ground and put drainage rock under the chamber.

T6-850 6 in. Square Wood Fence Post Anchor (4-Case) is rated 4.6 out of 5 by 7.

I've used the 6x6s, 4x6s, and 4x4 Oz-Posts now and have been very happy with the results, and am ordering more as soon as they are available (when?!). The 6x6s and 4x6s seem to be thicker metal, but the 4x4s are plenty strong. We used the 6x6s on end posts and gate posts. I'd read that the 4x4s would twist when hammered in, and that is true. On all, our objective wasn't fast installation, but to get the wood out of the soil, and save them from rotting in areas that are often wet. They've held up well for 2 years now with no warping or rotting. I hope that I'll never have to rebuild the fence, but just in case they do we also used bolts, and can easily remove a post if necessary. Overall, awesome product. (We need MORE!)

Rated 5 out of 5 by from Buyer beware of your local building codes These post anchors are strong and sturdy, unlike Titan deck anchors. I have a 952 sq ft, three level, freestanding deck which we used OZ T6-850/700 anchors to support it. However, I purchased two of the Titan's anchors to mount 11' patio umbrella and the anchors failed. So glad I didn't use the Titan product for my deck. Lastly, beware OZ-Post company representatives have not done a good job certifying this product. We contacted the company asking for data to provide the county inspectors, in order to approve our plan. We had to do the footwork and hire an engineer to certify our plan. Also, the plates will only fit T6-700 and below.

Rated 3 out of 5 by from Easy to pound in, difficult to keep from twisting while driving I installed 8 of these.I liked the Idea of not having to dig holes and fill with concrete. It was difficult to keep the OZpost from twisting while driving it into the ground. The result are posts which are not all square to each other. One would not drive through tree roots as advertised. Also when I purchased 6x6 post at Home Depot, they were bigger than the Ozpost and I had to cut a 1/8 inch from all 4 sides. This greatly increases the installation time. The OZpost are impossible to remove once installed. They are very sturdy once installed.

Rated 5 out of 5 by from great product Sturdy & did the job. Twisted a bit going into the ground but not enough to cause a problem. Built a pergola using these anchors worked great.

Rated 4 out of 5 by from A Game-Changer for Decks and Pergolas I bought these to create the footings for a pergola. I wanted something cheaper and faster than digging footings with an auger and filling with concrete. These allowed me, by myself, to create four footings in less than an hour with the help of a rented jackhammer. I am just over 6 feet tall and just under 200 pounds and I am very active, yet even I had a little trouble managing the jackhammer and the post all by myself. You can do this by yourself but I recommend two people do drive these things into the ground. I liked that these don't displace any dirt so there isn't any cleanup afterwards. Very fast. Experience: I was able to move the box of four by myself, and I could move the recommended 60-pound jackhammer by myself. However, I had to use a block of wood and a small 4 lb demo hammer to get the posts started in the ground so that I could setup the spacer and electric jackhammer without the whole mess falling over. Each Oz posts was nearly 20 pounds so you wouldn't want that to fall on your foot. The first 12 inches goes in very easily with a light sledge hammer, but I'm glad I got the largest electric jackhammer I could because the last 12 inches barely moves even under all that beating. I used ear muffs and the sound wasn't as loud as you'd think it would be jackhammering metal to metal. Issues: The spacer for use with a jackhammer fits the post anchors well, but is too wide in the center to really guide the jackhammer. Instead the jackhammer ends up deforming and beating both the spacer and the post anchor into submission. By the time I drove the fourth and final post, both the spacer and the center of the post anchor was toast. I had to turn the spacer several different ways to preserve the post during setting, sacrificing the spacer. Recommended for: Setting footings for fences and pergolas in short order without displacing any dirt to hide or move away. For large and fit DIYers that don't have access to a truck or friends that can help (mine were all on vacation or came down with a stomach bug).
