What buyers say on Amazon

★★★★★
This is a solid piece of hardware! … This bracket is heavy duty. It's just what we needed for our project. We were so impressed that we ordered a second one and will likely order more as we expand the project.

★★★★★
I used these for a ground-mount solar panel array. It slid over the post, which was cemented into the ground. The U-bolts work well and are grade 8. The notches for the bolts to go through are conveniently cut out so that it doesn't need to be exact in order for it to attach.

★★★★★
This thing is solid!! I have it connected to a 410 watt solar panel and it allows me to tilt and turn the panel based on the time of year… It's heavy and solid.

★★★★★
The plan is to mount 4 300 watt solar panels to it. This mount will easily handle that.
