Review: Nice metal things - I used these to hold my deck support beams in place. They worked great. But the cement deck post footing I poured sunk some and now I don’t know what to do. No fault of the post base. I hate diy projects, but I can’t afford to hire someone
Review: Nice heavy duty - They fit nice and snug on a 6x6 post. Did not use the supplied hardware. I opted for 5/16" concrete screws and black timber loks.

### ⭐⭐⭐⭐⭐ Nice metal things
*by S***P on February 21, 2026*

I used these to hold my deck support beams in place. They worked great. But the cement deck post footing I poured sunk some and now I don’t know what to do. No fault of the post base. I hate diy projects, but I can’t afford to hire someone

### ⭐⭐⭐⭐⭐ Nice heavy duty
*by J***S on February 24, 2026*

They fit nice and snug on a 6x6 post. Did not use the supplied hardware. I opted for 5/16" concrete screws and black timber loks.

### ⭐⭐⭐⭐⭐ Fence Upgrade!
*by B***L on April 25, 2026*

I used these post bases for a recent project and was very happy with how they turned out. They gave the posts a clean, finished look and made installation much easier compared to digging holes and pouring concrete. I personally didn’t use the anchors that were provided, but the bases themselves looked great and worked well for what I needed. If you’re building something that needs to be extremely secure or handling heavier loads, I’d recommend stepping up to a heavier-duty version for all of the bases. One of the biggest advantages was avoiding the mess, time, and hassle of mixing and pouring concrete for each post. Overall, these are a great option for lighter to medium-duty projects where you want a neat appearance and simpler install process.
