Postfix® Slotted Concrete Fence Post Brackets - Fit 4" x 4" Posts, 4 SETS - Clamp On, NO Drilling!

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.

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... :(

Fantastic product! These brackets fitted snugly onto my new fence posts and took all of 5 mins to fix into place. After measuring my posts I was a little unsure of which size to buy (4x4 or 4x5) but after a quick check of the POSTFIX website, their clear diagrams and measurements under the installation heading answered all my questions. Although the main and ancillary brackets come as sets direct from their website, buying the main postfix brackets separately through Amazon with their prime 1 day delivery gave me the opportunity to quickly check that they fitted onto my posts correctly before I committed to buying additional products to hang from them (which at the time of ordering I was still undecided i.e. Hanging baskets/Solar lights/wall baskets/plant pot holders ). I have now ordered some separate ancillary PF10 hanging basket adapter brackets direct from their website and am awaiting order of wall flower baskets from Amazon. Hopefully more of the POSTFIX products will become available through Amazon, especially if delivered through Amazon Prime as I'm impatient and don't like to wait! To summarise: these are fab, go order some now if you want to jazz up your fence posts!

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.

This product would be better value if it had greater clamping range. 4" x 4" versions were too big for a Jewsons 4 x 4 concrete post; too wide, so I had to pack it out with bits of lino-tile to stop the clamping screw bottoming out. A simple reduction in the horizontal dimension would obviate this and increase the grip. The slots are a bit limiting too; that could be improved; if you are fixing timber to these how do you do it?

I was really very happy with these. I needed to attach some wire fencing to a concrete fence post to plug a gap and didn't want to drill into the concrete fence posts. I can't comment on how great they are to fix hanging baskets to or anything, but for what I wanted these brackets did the job brilliantly. Fitted easily in 5 minutes with one screwdriver. Saved me a huge amount of stress and fiddling around. Thoroughly recommend.

Excellent well made product easy to install. Just the job for my climbing rose.

These fixings are a great idea. They do though have the potential to be better. Unfortunately not all concrete posts have the same profile. It would be good if the brackets came with an option regarding the thickness of the post between the front face and the slot where the panel goes.Something in the form of options for 30mm or 35mm or 40mm front face to wodden panel slot. That would be something that added value. It would have saved myself and I dare say others some knocking and banging and adroit use of the "workbench" to straighten them and then rebend them. I would/will buy them again - would be nice to have the option rearding the width of the claw as suggested above. Would pay an extra £1.00 / $1.5 to save the messing about. I would though think that there is no extra cost to making alternative sizes for the different front of post to slot thickness.
