Great product.
These for 4x4 posts easily. Look great and held up to winter and exposure to road salt spray thus far. I recommend using the mounting screws and sleeves provided for concrete mounting. Our contractor used tapcons which are rusting and I’ll have to redo in the Spring. Follow the instructions!! Ugh. But the product is excellent.

Nice brackets
I purchased these as deck railing bases for a deck renovation project. First let me say that I'm extremely impressed with the heaviness and stoutness of the anchors for use in my application. I'd installed the old anchors with through bolts and every single one of them (even though preserved with the "old" CCA preservative,) had rotted around the bolts. They've been a huge hassle to remove after 20+ years, and I ended up just cutting many of them off. I'm trying to "future proof" (not getting any younger!) the deck and these should make it much easier to replace posts should it become necessary. On first try my posts would not fit into the sockets which is when I discovered that every post (I cut my own from 4x4s) was oversized and varied as much 2-3mm between them (anywhere from 91-93mm.) When I measured the actual bracket, it came in at 90mm. I ran each through my table saw (set at exactly 3.5") which produced a fit with just a smidge of wiggle room. Personally, I don't think I would use these on concrete, but for my application they should be fine. We'll see how well they hold up in the real world.

Great value! Has all you need to attach.
Out of pure procrastination, I don't usually leave reviews, but with this product, I just had to do it! I'd give more stars if I could. Usually when I have a project like this I spend too much time at Lowe's or Home Depot looking for the attaching bracket and then all of the hardware to go with it, while also hoping I bought the right sizes, and don't have to run back out. This came with pretty much everything I needed for probably cheaper than I could have bought it for at the big box hardware store. Brackets are well built, sturdy, and all the hardware is included... Whether or not you're attaching to wood or concrete. Once I had these on hand it was a quick install. Great job to the seller. I would definitely buy these again! My only complaint is I could only buy them by fours. I only need three but it was still cheaper to do it this way then do it locally. Plus, again, it had everything I need.

Saves time, safer, more efficient
These were a perfect fit for my 4 x 4’s and made the deck building much easier. These are quality materials. I am confident that will outlast the deck itself.

Post Screws Rusted Days After Install.
Overall I would say these are solid bases. My largest complaint is that the screws used to attach the post to the base rusted within days of being installed (the attached photo is one of the lesser rusted ones. Several had already begun to leave rust streaks on the brackets). I had to go back out and replace every single screw with a reputable black deck screw. If I had another complaint, it would definitely be that the Philips head on the lag screws did not hold up well when driving several of the screws in. However, I didn't feel that issue was a dealbreaker because the ones that did strip were able to be fully seated with a socket. Just took a little longer when that happened. When compared with prices at big box stores for similar products, the value is certainly there. Just be sure to purchase alternative screws for attaching the posts to the bases unless you for some reason installed these indoors.

4 x 6 Post Braket
Does not fit a 4 x 6 post as advertised, post has to be trimed/modifed to fit inside the bracket, but it is a well built unit just be prepared for some extra work.

Great brackets, terrible supplied concrete anchors
The actual post brackets are great, sturdy, well constructed. The concrete anchors though are awful, too spindly and inadequate for the majority of jobs. I bought some 5/16 3” anchors and slightly enlarged the bracket holes and then it was great.

Sturdy Construction
These mounts are good quality and sturdy enough to easily support 6 x 6 posts. All the fastening hardware was included for both wood deck mounting and concrete pad mounting.
