4.1. C-Clamp Installation
- Attach the C-clamp base to the bottom of the main pole.
- Position the main pole assembly at the desired location on your desk.
- Tighten the C-clamp screw until the mount is securely fastened to the desk. Ensure the desk thickness does not exceed 2.4 inches (6 cm).
- Slide the horizontal arm onto the main pole and secure it at the desired height using the provided hex key.
4.2. Grommet Installation
- If your desk has a grommet hole, remove the grommet cover.
- Assemble the grommet base components according to the diagram in the included quick start guide.
- Insert the main pole through the grommet hole and secure the base from underneath the desk using the provided plate and screw.
- Slide the horizontal arm onto the main pole and secure it at the desired height using the provided hex key.
4.3. Attaching Monitors
- Carefully attach the VESA plates to the back of your monitors using the appropriate VESA screws (75x75mm or 100x100mm). Use washers and spacers if necessary to ensure a secure fit without overtightening.
- Slide the monitors (with VESA plates attached) onto the ends of the horizontal arms. Ensure they click into place or are secured with the locking mechanism.
- Adjust the tension of the arm joints using the hex keys to support the weight of your monitors. This will prevent sagging or unwanted movement.
