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

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.

Fence Upgrade!
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.

Very nice quality and fit my 4 x 4 posts with no problem. Also appreciate the anchors and screws that were shipped with the bases.

Sturdy.
Sturdy and reasonably priced. Easy to install. The caps are holding up well but after a short time, the hardware started rusting which I didn’t expect.

Nice and sturdy
These work out perfect. We’re cheaper than going to the Home Depot and are very stable. Metal is thick and even comes with wedge anchors in stainless. I would recommend.
