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.

These are great little brackets, but only just man enough for my intended use, which wasn’t what they were intended for, but have worked nonetheless!

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?

My posts are 90mm wide and 29mm deep and the clamps fit perfectly. They are easy to tighten and rock solid when fitted. Note: I will cut off the excess thread to make them look tidy once the whole job is finished.

I have used these previously on concrete posts in my garden, found them OK for what I wanted (something to secure plant tie backs to - no great load on them). I ordered a second lot but they don't fit on other concrete posts in the garden - no difference in the bracket size, bit I didn't realise that there was variation in the lip width on my concrete posts and assumed that these would be "one size fits all" - they aren't. Fairly expensive for what they are, a bit of formed tin and a long roofing bolt.

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