Customer Questions & Answers

I want to us theses for the footings on a play set that will stand 4 feet high. Are these post anchors suitable for that

Asked by: Andrew
I think they would work very well. We use them on signs that stand 8 feet high, and they have always been rock solid.

Good solid product, worked well, was disappointed that is was made in China, and the fact that the tapered section of the post/spike was slightly twisted and the post turned clockwise when driving it into the ground. I learned to compensate by starting the post with a slight turn counter clockwise when I starting setting the post. Overall made a tough job much easier.

Rated 5 out of 5 by from Excellent product. This is a good anchor system. No need for digging, cementing, etc. Went through tough ground fairly well. It helps to have a small metal plate to place into it as you are pounding it in. That will keep your wood from splitting inside and getting wedged tight.

Rated 5 out of 5 by from Sure beats digging holes My son had purchased these when he built a picket fence at the top of a retaining wall in back of his house. I was sold on them from that experience. When I needed to replace my 6 ft high fence around my yard, I immediately bought these. They are much easier to use than digging holes (his ground is clay and sand stone) and since the posts do not have contact with the ground, there is less chance of rot. These support my fence well. I would recommend buying the level for these. My son made his own hammer spacer, so we did not need to purchase this.

Rated 5 out of 5 by from OZ-POST Install We purchased 48 of the T4-850 OZ-Posts and they worked just as advertised. We made sure we have our corners and string lines correct before we started and the process of installing these posts save time and labor. We started installing almost 400 linear feet of fencing and were able to install of all the OZ-Post supports, 4" wooden support posts and 90% of the 3-rail runner supports in about 8 hours with 4 people. Overall a great product. On average we put down each post in about 6 minutes after all the measuring was done with a 75lb jack hammer rental.

Rated 3 out of 5 by from Great when it works. I had 10 post to install. The first 6 went in pretty well. I used a 9" length of 4x4 and a sledge hammer. had to use some steel plates under the 4x4 cause the wood tends to split on the small round plate when hammered in. It wasn't too hard to keep them level. Then, I started hitting roots. I don't know what the size of the roots were but I couldn't keep the posts level and it was really tough hammering them in. I had to pull a couple of them and start over. One of the ones I pulled was bent from trying to go through a root. there's a comment on the Oz-Post site that says the anchor is designed to cut through roots. Don't believe it. If you have area with no roots or rocks, these are great. Otherwise, you're in for a tough haul. Then again, I don't know what else you could use in those situations.
