The Ergotron LX Pro Dual Stacking Arm (45-714-293) is a dual-monitor mounting solution designed to position two compatible displays vertically on a single desk-mounted arm system. Its low-profile C-clamp attaches to the desk edge, helping keep the workspace organized while allowing the monitors to be adjusted for comfortable viewing.
Part of the Ergotron LX Pro range, this monitor arm combines adjustable movement, integrated cable management, and a modular design for professional and home-office workstations.
Key Features
- Vertical dual-monitor configuration: Positions two compatible monitors in a stacked arrangement to make more effective use of desk space.
- Adjustable positioning: Supports monitor height adjustment, tilt, pan, and screen rotation for flexible viewing.
- Low-profile C-clamp: Attaches to a compatible desk edge without requiring a grommet mounting hole.
- Integrated cable management: Helps route monitor cables along the arm to maintain a tidier workstation.
- Dark grey finish: Provides a coordinated appearance for modern office and workstation setups.
Monitor Compatibility and Adjustment
The LX Pro Dual Stacking Arm is designed for two monitors measuring up to approximately 27 inches each, subject to display weight, dimensions, and mounting compatibility. The total supported load is 8–44 lb (3.6–20 kg), with an individual monitor weight range of 4–22 lb (1.8–10 kg) per display.
The arm provides up to 13 inches (33 cm) of lift, along with adjustable tilt, pan, and rotation. Monitor size is a guideline rather than the sole compatibility requirement: each display must also meet the weight limits and VESA mounting requirements.
Mounting and Desk Requirements
This model uses a low-profile C-clamp mount intended for desk surfaces approximately 0.47–1.57 inches (12–40 mm) thick. Check the desk edge, underside clearance, and monitor arrangement before installation to ensure the mount fits the intended workstation.
The monitor interface supports VESA MIS-D mounting patterns of 75 × 75 mm and 100 × 100 mm. Displays without a compatible mounting pattern may require a suitable adapter, which should be verified separately.
Typical Applications
- Office and home-office workstations
- Dual-screen productivity setups
- Data analysis and administrative work
- Work areas where vertical monitor placement helps conserve desk space
DC Supplies Product Note
Before ordering, confirm that both monitors meet the supported individual weight range, the combined load is within capacity, and the desk is suitable for the low-profile C-clamp. For stacked installations, the maximum outside height of each display should also be checked against the manufacturer's stacking guidance.
