Rated 4.5 out of 5 by 13 reviewers.
Rated 5.0 out of 5.0 by Extremely strong post base Simpson Strong-Tie is the post base to have. I used 4 of these for a pergola on a cement pad in order to keep the posts from rotting. The standoff is good and the metal is thick and sturdy enough that I have no concerns about it. Even after 4 months of wear and surviving some unseasonably heavy rains there is no visible corrosion. These bases seem to be a little expensive for what they are, but that's fine. Not that if you are using rough-cut lumber than the posts will not fit in this bracket without some small notches.

Rated 5.0 out of 5.0 by Works great Works great and easy to use. Be sure to tighten down securely before attaching post. April 29, 2014
Rated 5.0 out of 5.0 by Easy to use I was able to set the post into place with very little effort. Went back to buy more to finish off my cooking sections April 22, 2014
Rated 5.0 out of 5.0 by Excellent post base product Easy to install adjustable post base. Love the flexibility of the mounting bolt hole as well as the screw/nil attachment holes for the side of the wood post. November 11, 2014
Rated 4.0 out of 5.0 by You may need these I bought these as part of a porch addition. I had 6x6 posts on top of 12x12 concrete piers and you need a bracket which makes a gap between the concrete and the wood to comply with code unless you want to use ugly, expensive treated posts. The brackets which you can pour into the concrete are a little cheaper, but these you connect to the concrete with a redhead bolt and they allow for a little fudging - which I generally need. My only gripe is that they are so expensive, but these are priced competitively with all comparable brackets. September 16, 2014
Rated 4.0 out of 5.0 by Building a Pergola I was building a 12 x 16 pergola and used these for the 6x6 post to anchor them into the concrete. They worked great and are very strong. May 15, 2014
Rated 4.0 out of 5.0 by Great Product wish they adjusted vertically I would have given them 5 Stars but they are a bit pricey. I needed to use them without a column support; direct from the cement to the 3x 2x8 beam. This required the use of a shim to make up the difference in size of the beam versus a 6x6. If I used a 6x6 it would have been a bit of a tight fit. Watch out for the sharp edges; wear gloves when working with this product. September 30, 2014
Rated 5.0 out of 5.0 by Worth every penny. Very easy to install and the ability to adjust the settings is a must have. September 2, 2014
