### ⭐⭐⭐⭐⭐ For mast antenna
*by J***I on June 26, 2025*

Works well

### ⭐⭐⭐⭐⭐ Just what I needed
*by J***C on October 12, 2024*

Works

### ⭐⭐⭐⭐ Does The Job
*by T***J on June 11, 2021*

Used these clamps to attach a 1 inch electrical conduit pipe to a 1.25 inch pipe to mount a TV antenna. Worked as expected and a good value. I would just avoid overtightening the clamps because, at least in my case, the clamps started to spread apart when I tried to apply a lot of force.
