4. Setup and Installation
Before beginning installation, ensure your desk is sturdy enough to support the monitor arm and your monitor's weight. Clear your workspace and gather all necessary tools.
4.1 Important Notice Regarding Arm Rotation
Please note the following:
- Screw Direction: The direction of the screws in the connecting part may differ from the images in the instruction manual. This is a normal adjustment made during shipping to accommodate packaging and does not affect usage. Please proceed with confidence.
- Arm Rotation Stiffness: The rotating connection part may feel stiff and not rotate easily by hand before a monitor is attached. This is intentional to prevent unintended rotation during installation. Once the monitor is securely mounted, the arm will rotate smoothly.

4.2 Choosing a Mounting Option
The KOORUI KR10G offers two installation methods: Desk Clamp and Grommet Base. Choose the method best suited for your desk.

4.3 Desk Clamp Installation
This method is suitable for desks with a thickness between 0.4 - 2.0 inches (10 - 50 mm).
- Attach the desk clamp to the main pole of the monitor arm.
- Position the clamp on the edge of your desk.
- Tighten the clamp screw until the arm is securely fastened to the desk. Ensure it is stable and does not wobble.
4.4 Grommet Base Installation
This method requires a pre-drilled hole in your desk with a diameter of at least 0.4 inches (10 mm) and is suitable for desk thicknesses between 0.4 - 2.0 inches (10 - 50 mm).
- Disassemble the desk clamp from the main pole and attach the grommet base.
- Insert the main pole through the grommet hole in your desk.
- From underneath the desk, secure the grommet base using the provided hardware. Tighten firmly to ensure stability.
4.5 Attaching the Monitor
The monitor arm supports VESA patterns of 75x75mm and 100x100mm.
- Attach the VESA plate to the back of your monitor using the appropriate screws from the hardware kit. Ensure the plate is securely fastened.
- Carefully slide the monitor (with the attached VESA plate) onto the arm's VESA head.
- Secure the monitor to the arm using the provided thumbscrews or locking mechanism.

5. Operating and Adjusting the Monitor Arm
The KOORUI KR10G monitor arm offers extensive adjustability to achieve your optimal viewing angle and ergonomic setup.
5.1 Height Adjustment
The arm can be adjusted vertically along the main pole. Loosen the collar clamp on the main pole, adjust the arm to the desired height (up to 16.9 inches / 430 mm), and then tighten the clamp firmly to secure it.

5.2 Tilt, Swivel, and Rotation
The monitor arm allows for multi-directional adjustments:
- Tilt: Adjust the monitor screen ±72° (up/down) to reduce glare and find a comfortable viewing angle.
- Swivel: Rotate the monitor 90° left or right at the arm joint.
- Rotation: Rotate the monitor 360° from landscape to portrait orientation.

5.3 Cable Management
Utilize the integrated cable clips along the arm to route and organize your monitor cables. This helps maintain a clean and clutter-free workspace.

6. Maintenance
Regular maintenance ensures the longevity and safe operation of your KOORUI KR10G monitor arm.
- Cleaning: Wipe the arm with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish.
- Tightness Check: Periodically check all screws and connections, especially the desk clamp/grommet base and VESA plate screws, to ensure they remain tight. Re-tighten if necessary.
- Movement Check: Ensure all joints move smoothly. If any joint becomes too loose or too stiff, use the provided Allen wrenches to adjust the tension screws.
7. Troubleshooting
If you encounter any issues with your monitor arm, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Monitor arm is unstable or wobbles. | Mounting base is not tight enough. | Re-tighten the desk clamp or grommet base screws firmly. Ensure the desk surface is flat and stable. |
| Monitor sags or does not hold position. | Joints are too loose; monitor weight exceeds capacity. | Tighten the tension screws on the arm joints using the provided Allen wrenches. Verify your monitor's weight is within the 22.0 lbs (10 kg) limit. |
| Monitor arm is difficult to move or adjust. | Joints are too tight. | Loosen the tension screws on the arm joints slightly using the provided Allen wrenches. Remember the arm may be stiff before a monitor is mounted. |
| VESA plate does not fit monitor. | Incorrect VESA pattern. | Confirm your monitor has a 75x75mm or 100x100mm VESA pattern. This arm is not compatible with other VESA sizes. |
