Rated 5.0 out of 5.0 by Durable and perfect for my building needs. This piece reinforced my post when I did an addition to my home. 4by4 posts fit perfectly and were easy to manuvear. May 11, 2015
Rated 4.0 out of 5.0 worked well for what it is designed for bought this for support on awning for a storage shed. worked well without having to sink support post deep into ground, thereby saving on cement and having to dig deeper hole and since i am 71 years young, saved engery too. March 1, 2014
Rated 5.0 out of 5.0 by Makes for quick work Living in the Pacific Northwest - we get a lot of rain, actually no more than many other areas of the US in terms of overall volume - we just get a little bit everyday for a long time.... We have a lot of bark dust, and ground cover in attempts to keep the soil from running, all of this keeps the moisture trapped in and around posts - using these post bases makes quick work of replacing rotting posts. Please keep in mind, these are not intended for fence posts - but I use them anyway - just not within two spans of a gate - they don't provide any lateral (side to side) strength. January 13, 2015
Rated 5.0 out of 5.0 by Does what it's suppose to 4X4 post bracket that gets cemented into the ground. I used this bracket for a fence post. Note that the post must be supported at the top, or this will not work. The material is steel and has a galvanized coating. Steel is relatively thick and the galvanized coating seems good. Price is very reasonable and it did what it was suppose to. October 15, 2014
Rated 1.0 out of 5.0 by need a variety I needed the cb44 system that at one time you had. I had to buy long bolts to go through the holes on the inside of the product so it would grip the cement. August 5, 2014
Rated 4.0 out of 5.0 by Did its job just make sure you line them up facing each other so you can get the beam between the posts. September 16, 2014
Rated 5.0 out of 5.0 by 4x4 Post Base Works great for the privacy trellis. Due to the amount of rocks, had to come up with alternative to setting 4x4's into concrete directly. July 22, 2014
Rated 5.0 out of 5.0 by Good quality Got the job done. Just don't push too far down into concrete. May 13, 2014
