| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening nuts, potentially deforming the pipe or U-bolt. | Tighten nuts evenly to a snug fit, then apply an additional 1/4 to 1/2 turn, or until secure. Avoid excessive force. |
| Using the wrong size U-bolt for the pipe diameter. | Always confirm the nominal pipe size and cross-reference with the U-bolt's internal dimensions (A and B) before installation. |
