Setup and Installation
Follow these steps carefully to install your Maclean MC-884 Dual Monitor Desk Mount.
Step 1: Attach the Desk Clamp
- Place the main pole assembly onto your desk.
- Adjust the desk clamp to fit your desk thickness (10mm to 88mm).
- Tighten the clamp screw securely until the mount is stable on the desk. Ensure it is firm but do not overtighten.

Step 2: Attach VESA Plates to Monitors
- Carefully place your monitor face down on a soft, clean surface to prevent scratches.
- Align a VESA mounting plate with the VESA holes on the back of your monitor (75x75mm or 100x100mm).
- Secure the VESA plate to the monitor using the appropriate screws from the hardware kit. Do not overtighten. Repeat for the second monitor.


Step 3: Mount Monitors to Arms
- With assistance, carefully lift each monitor and slide the VESA plate attached to the monitor onto the corresponding arm bracket.
- Ensure the monitor is securely seated on the arm bracket. Tighten any safety screws or clips if provided.

Step 4: Cable Management
- Route your monitor cables (power, video, etc.) through the integrated cable management clips along the arms and down the main pole.
- Close the clips to hold the cables neatly in place, reducing clutter and preventing damage.

Operating Instructions
Adjusting Monitor Position
The Maclean MC-884 offers full motion adjustability for optimal viewing comfort.
- Height Adjustment: Loosen the collar on the main pole to slide the entire arm assembly up or down. Retighten the collar once the desired height is reached.
- Tilt Adjustment: The monitor can be tilted up or down to reduce glare and improve viewing angles. Loosen the tilt knob behind the VESA plate, adjust the angle, and then retighten.

- Swivel Adjustment: Each arm can swivel horizontally up to 180 degrees at two pivot points, and the entire arm assembly can pivot 360 degrees around the main pole. This allows for flexible screen positioning.
- Rotation Adjustment: The VESA plate allows for 360-degree rotation, enabling you to switch your monitor between landscape and portrait orientations.
Always support your monitor when making adjustments to prevent accidental drops or damage.
Maintenance
To ensure the longevity and proper function of your Maclean MC-884 Dual Monitor Desk Mount, follow these simple maintenance guidelines:
- Cleaning: Wipe the mount with a soft, damp cloth. Avoid using abrasive cleaners or solvents, as they may damage the finish.
- Inspection: Periodically check all screws, bolts, and connections to ensure they are tight and secure. Loose connections can lead to instability.
- Lubrication: No lubrication is typically required for the moving parts. If any joints become stiff, consult customer support.
Troubleshooting
If you encounter any issues with your monitor mount, refer to the following common problems and solutions:
- Mount is unstable: Ensure the desk clamp is tightened securely to the desk. Check that the desk surface is stable and can support the weight of the mount and monitors.
- Monitors are not level: Adjust the tilt and rotation mechanisms on each VESA plate to align the monitors. Ensure the main pole is vertically straight.
- Difficulty adjusting monitor position: Check if any adjustment knobs or screws are overtightened. Loosen them slightly to allow movement, then retighten to hold the position.
- Cables are messy: Re-route cables through the integrated cable management clips, ensuring they are properly secured.
