Review: Easy to recommend - I bought these for 90 mm concrete fence posts; however, they are actually designed and advertised for 100 mm ones. My mistake! Still, I was able to improvise and use some hard plastic wedges to make them fit. Despite some initial reservations I had about their strength—as they are made of thin metal—they are plenty strong enough for my purposes. If you need to attach low-weight objects to your concrete fence posts, then I can happily recommend these.
Review: Shame there aren't more sizes to choose from - I was looking for a way to mount a very heavy vertical garden made from pallets to my fence posts. These seemed like a great solution, I had planned to use two on each side, with some heavy duty cleats to distribute the weight. It was late at night when I ordered and I couldn't be bothered to go out and measure the posts. I assumed that 4x4 inches was a standard size and guessed that would be the size of my posts... I was wrong. "No worries" I thought, "I'll just return these and try to find another size!" Oh but wait, there aren't any to fit a 3 1/4" post. 😱 The company website shows a "universal" model, but I couldn't find it to buy. I also noticed that with that model, you have to bend it yourself to fit. Which might be fine if you have the strength and tools to do that. But I doubt I'd be able to adjust it well enough for it to be secure and be able to hold the pallet, soil, and plants securely to the fence. It's such a shame because these would have been perfect otherwise. And there doesn't seem to be anything else on the market of similar quality, that can do the same thing. Back to the drawing board for me... :(

## Questions & Answers

**Q: if you wanted to use these to extend chicken wire onto the top of an existing fence, what would you need to buy timber etc to do so?and where to find?**
A: Not knowing the thickness of the chicken wire. You would need to attach some wooden frame to the post fixes, with the chicken wire attached. I found the the post fixes to be very solid.

**Q: Can I use these to attach a wooden fence post to concrete? thanks**
A: Would not recommend for two reasons. First, although advertised as suitable for 4" posts they were too big for mine and required packing out in order to get a grip.  Second, in order to fasten anything to th ebracket you need access from its rear face, i.e. the one which is hard up against the concrete post.

**Q: I need 30 packs to start and then probably another 120 packs after that. Can you provide some discount for that quantity please?**
A: You'll have to contact the manufacturer or supplier directly

**Q: Hi would you have an option for 80mm concrete posts?**
A: The brackets are made to fit a 100mm post only. Suggest you find brackets specifically made for 80mm posts.

### ⭐⭐⭐⭐⭐ Great easy-to-fit brackets.
*by A***S on 30 October 2023*

These are quite expensive for what they are but they do the job well. For some reason my concrete posts are relatively narrow but the fitting range was given in the product information and the brackets clamped down fine on my posts. Use a large flat blade screwdriver to tighten up onto the posts. I have used them to mount metal railings by fixing the railings' brackets to these brackets. Brilliant...they hold fast and no need to try to drill into reinforced concrete. If you want to fit something to a concrete fence post then these are just the job.
