## Customer Reviews

### ⭐⭐⭐⭐⭐ They fit perfectly
*by I***S on June 10, 2024*

They are exactly 4” as advertised. They fit my 4” X 3/16 square pipe, the top flange is flush with the outside of my pipe. The fit inside the pipe seemed to be sufficiently tight. I’m happy

### ⭐⭐⭐⭐⭐ Thick and strong

### ⭐⭐⭐⭐⭐ Caps
*by T***Y on June 2, 2025*
