- Ensure the hole diameter is between 0.39 inches and 0.8 inches.
- This method is suitable for desk thicknesses between 0.39 inches and 1.96 inches.
- Secure the grommet base through the hole and tighten from underneath the desk.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Monitors are not stable or sag. | Mounting screws are loose; monitor weight exceeds capacity. | Tighten all mounting screws. Verify monitor weight is within 17.6 lbs per arm. |
| Difficulty adjusting monitor height. | Collar on the pole is too tight. | Loosen the collar slightly before adjusting height, then retighten. |
| Monitors do not fit the VESA plate. | Incorrect VESA pattern or monitor lacks VESA holes. | Ensure monitors have 75x75mm or 100x100mm VESA patterns. For monitors without VESA holes, a separate adapter may be required (e.g., HUANUO HNMUA4 VESA Mount Adapter). |
