It works as it should. Great value
These function well for mounting low voltage hardware on poles (ie, cameras, tag readers, sensors...) I bought these because the local home improvement stores didn't have what I needed. I recommend these.

Very high quality.
Although I ended up not being able to use the u-bolt it was well made and much heavier that the other one I purchased at the blue box. Amazon took care of me on the return. Great product. ๐
