Rated 5.0 out of 5 by 4 reviewers.
Rated 5.0 out of 5.0 by Heavy Duty Brackets! I bought these brackets to anchor the posts for the roof over my back porch. The previous roof had been taken down by high winds and I wanted to upgrade to a more secure fastening system. These brackets really fit the bill. They are made out of very heavy gauge steel and bolt to the concrete base as well as to the post itself. While they are a little pricey, I think they are a good value and should last a lifetime.

Rated 5.0 out of 5.0 by Heavy Duty I have not installed yet, but these bases are very sturdy/heavy gaugle metal. They should be a snap to install on my threaded J-bolts. July 15, 2014
Rated 5.0 out of 5.0 Expensive but worth it for the right job Simpson brackets are good and can be adapted to the job. This particular bracket is bullet proof and very sturdy for heavy loads. Downside they are very expensive and should only be used for heavy jobs if required. Simpson also makes a lighter 6x6 bracket that is much cheaper and available in store. September 11, 2012
Rated 5.0 out of 5.0 by Heavy Duty This is what you want for a real stability and strength. Too bad they're not in the store, they only carry a lighter duty version. May 28, 2011
