4. Setup and Installation
Before beginning installation, ensure you have all components as listed in the product packaging. Choose a sturdy desk or table capable of supporting the weight of the monitor arm and your monitors.
4.1 Mounting Options
The ULTRARM monitor arm offers two primary mounting methods: C-clamp and Grommet mount. Select the option best suited for your desk.

- C-clamp: Ideal for desks with an edge, supporting thicknesses from 0.6" to 3.3" (1.5 to 8.5 cm).
- Grommet: Requires a pre-drilled hole in the desk, supporting thicknesses from 0.6" to 1.9" (1.5 to 4.8 cm).
4.2 VESA Compatibility
The quick-release VESA bracket supports both 75x75mm and 100x100mm mounting patterns. Ensure your monitors are compatible with these VESA standards.
4.3 Monitor Arrangement Assessment
When planning your monitor setup, especially for vertical or horizontal arrangements, consider the dimensions and VESA mounting locations of your screens. The following diagram provides guidance for calculating required space.

4.4 Assembly Steps
- Securely attach the chosen mounting base (C-clamp or Grommet) to your desk. Ensure it is tightened firmly to prevent movement.
- Insert the main pole into the mounting base.
- Slide the monitor arm(s) onto the pole and adjust to your desired initial height. Tighten the locking mechanism.
- Attach the VESA plate to the back of your monitor(s) using the provided screws.
- Carefully slide the monitor(s) with attached VESA plates onto the monitor arm's VESA head until it clicks into place.
- Adjust the tension of the gas spring arm to match the weight of your monitor(s) for smooth movement. Refer to the operation section for details.
5. Operation and Adjustments
The ULTRARM monitor arm provides extensive adjustability to create an optimal viewing experience and reclaim desk space.

- Height Adjustment: Utilize the gas spring lift for smooth vertical movement. Adjust the tension screw on the arm to ensure the monitor stays at the desired height. Turn clockwise to increase tension for heavier monitors, counter-clockwise for lighter monitors.
- Tilt: The monitor can be tilted +25 to -25 degrees to reduce glare and optimize viewing angles.
- Swivel: Swivel the monitor 180 degrees horizontally to share your screen or adjust your viewing position.
- Rotation: Rotate the monitor 180 degrees to switch between landscape and portrait orientations.
- Extension/Retraction: The articulating arm allows you to extend the monitor up to 25 inches (64 cm) or retract it closer to the pole, with a minimum distance from the wall of 3 inches (7.5 cm).

The modular design supports various monitor configurations to suit your workflow.


6. Maintenance
To ensure the longevity and optimal performance of your ULTRARM monitor arm, follow these simple maintenance guidelines:
- Cleaning: Wipe down the arm and pole regularly with a soft, dry cloth. For stubborn marks, a slightly damp cloth can be used, followed by drying. Avoid abrasive cleaners or solvents.
- Inspection: Periodically check all screws and connections to ensure they remain tight. Re-tighten if necessary.
- Gas Spring Tension: If your monitor begins to sag or is difficult to adjust, re-adjust the gas spring tension screw as described in the Operation section to match the monitor's weight.
7. Troubleshooting
If you encounter any issues with your ULTRARM monitor arm, refer to the following common troubleshooting tips:
- Monitor Sags or Won't Stay Up: The gas spring tension is likely too low for the monitor's weight. Increase the tension by turning the adjustment screw clockwise.
- Monitor is Difficult to Move Up or Down: The gas spring tension might be too high. Decrease the tension by turning the adjustment screw counter-clockwise.
- Arm Feels Loose or Wobbly: Check all mounting points, including the desk clamp/grommet and the connections between the arm segments and the pole. Tighten any loose screws. Ensure the desk itself is stable.
- Monitor Not Level: Check the VESA plate attachment to the monitor and the arm. Ensure the monitor is securely seated on the quick-release bracket. Minor leveling adjustments can often be made by slightly rotating the monitor on the VESA head.
- Cable Management Issues: Ensure cables are routed through the integrated cable management clips or channels to prevent snagging and maintain a tidy appearance.
