Will bend. Do not use for freestanding structure. *by T***M on Reviewed in the United States on May 16, 2020* The media could not be loaded.  Be careful with these....My intention was to use these for a 14x14 pergola with 6x6 posts.I dug x4 8”x24” round holes for footings, filled them with concrete and set the post holders.I waited 48 hours for the concrete to cure and they were well set, zero budge or wriggle.After cutting the 6x6s to length they were installed vertically and I started to build the pergola.I noticed the movement but figured once I installed the lag bolts on the beams the movement would stop. It didn’t.Next morning the whole structure had shifted with the bent metal and was swaying in the wind.I’ve taken down the pergola due to safety and now have to work out how I remove the brackets and brake up the concrete. Next time I’ll set the posts into the ground which with 20:20 hindsight as I’d already dug the holes for the footings I should have just set them in the ground. ### ⭐⭐⭐⭐⭐ Great price, solid build *by N***K on Reviewed in the United States on September 7, 2019* These are great for the price and as far as I can tell they'll do just fine for years and years to come. Doing a purgola project and coming in around 1200 bucks altogether saving a little here and there was big when the other Simpson brand, while I'm sure the quality is there, are going to run you about 3 times as much. I ran a planer on all sides of the 6x6 posts and at the bases and they fit right into the boots just fine. Word too any fellow novices out there, make sure you're good n square at the base! Haha, save you a couple hours of correcting down the line but anyhoos, highly recommend these. ### ⭐⭐⭐ Not for large structures *by C***7 on Reviewed in the United States on December 3, 2019* I gave them a 3 just for the price, but dont expect these to be square. I bought enough to do my 40x16 camper shed with 16ft post and a lot is left to be desired. There is so much post movement I'm having to figure out how to brace this shed. So if your like me and didnt want to spend the 90 bucks a pop for the ones with 4 rebarb do yourself a favor and just buy the more expensive ones. These are probably ok for smaller patios but not for larger structures. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/109957919-mtb-supply-4x3-5-1pc-u-shape-fence-post-holder](https://www.desertcart.vu/products/109957919-mtb-supply-4x3-5-1pc-u-shape-fence-post-holder) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-07*
