### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good Quality
  

*by A***Z on Reviewed in the United States on July 8, 2024*

I used this cable for an off grid Solar install.  It worked perfectly and the flexibility on the cable allowed me to dress the install.  I ran both wires through a 3/4" conduit, I probably should have used 1".  The cable pulled through well, but was tight going around the corners.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars
