Customer Questions & Answers

Sturdy enough for storms?

I am looking at building a light 6 foot fence (using wood poles, and supports, but primarily wire). I want to use these since the fence would ideally be temporary, having used these do you feel that they would be sturdy enough to hold up the fence in New England weather? Please only respond if you have purchased and used this item. Thank you!

I live in Kern County, Ca.. We get some good strong winds. I have used these years ago and they still look great.

You would probably need an auger to drill through the surface of the asphalt first.

T4-850 4 in. Square Wood Post Anchor is rated 4.6 out of 5 by 50.
Rated 1 out of 5 by from 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.

Rated 4 out of 5 by from I used the Oz-Post to support an 8 foot, 60... I used the Oz-Post to support an 8 foot, 60 pound birch log that we use as a sign post at our lake house. Overall, I was pleased with the product. Even in relatively sandy soil, the post is nicely secured. There are a couple of caveats however. If you are using the post as a one-off like I did you will probably use a sledge hammer and scrap 4X4 to drive it into the ground. Doing so makes it difficult to keep the post plumb and level. Also, the post has a tendency to rotate slightly when being driven making it a challenge to keep it perpendicular to my project frontage. Finally, the sledge and 4X4 method may slightly deform the base requiring a little finesse with the final post install. All that notwithstanding, I would use in again without hesitation.

When it hit a Rock/Root it turned off center. it was good easier to true up the fence when it went into the ground at a Slight Angle. I may use them again and cement them into the ground because the post will not touch the ground in the North West.. it was more controllable with a sledge hammer than an Electric jackhammer..

The anchor is made of very thin, low quality steel. The lower end (below ground) was twisting while I was driving the anchor into the ground. At the same time, the upper end (holding the wood post) was bending like a balloon, making it difficult to bolt the post to the anchor.. This anchor is too expensive for this poor quality, I would not buy again.

Take your time to align it as it enters the ground. Definitely faster than digging a hole and using concrete or foam. It appears to lock into the soil. Definitely use coated screws to install post. There is a gap between the post and oz support which requires the use of spacers to align the post. A bit pricey.

It is indeed an “anchor” extending as it does some 18-20 inches into the ground. The box into which the 4x4 fits has several holes on each of the four sides for installing screws to secure the 4x4 (I used lag bolts).

Must be careful to check for levelness along the way. My 72 year old husband installed them with only a sledge hammer, several pieces of 2 X 4 and my nagging to make sure they stayed straight.
