## Questions & Answers

**Q: Does the 4x4 and 6x6 refer to the post size or base size?**
A: 4x4 is post size that can be used and 6x6 is the base size

**Q: It looks like there is no stand off for water unlike some other designs? Does this rust?**
A: mine has been up and in the elements for 2 years in Oregon. We get a lot of rain. I have seen no sign of rust.

**Q: would these work to secure an 8 foot tall pergola to pavestone?**
A: I think they would work great for that. They are pretty heavy duty, and they are powder coated paint so they should hold up well outdoors.

**Q: It says this is a 6”x6” post base, within the q&a I see a lot about 4x4 and even where it says the base is 6x6.  Is this for a 6x6 post or 4x4?**
A: The thin plate that mounts the support to another surface is 6" x 6". The upper part holds a 4' by 4" post.

### ⭐⭐⭐⭐ 4x4 base support
*by M***S on July 4, 2025*

The 4x4 base support seems like it will work well for the price it's a good product. But the concrete anchors they Supply with it are absolute garbage. Don't even waste your time just go get some good ones it will save you a lot of headache.
