The Ergotron 45-518-216 MXV Desk Dual Monitor Arm is a white dual-display desk mount with an under-mount C-clamp. Its V-shaped design provides side-by-side monitor positioning while the under-mount clamp attaches beneath the desk edge for a low-profile mounting arrangement.
Overview
The 45-518-216 supports two displays with a combined weight capacity of up to 40 lb (18.1 kg). Each monitor can weigh 7–20 lb (3.2–9.1 kg). The mount provides integrated height adjustment and independent display positioning for a dual-monitor workstation.
Dual-Monitor Configuration
The MXV is designed for two side-by-side displays. Each display attaches using VESA-compatible monitor hardware, while the articulated arms allow the screens to be positioned individually.
Under-Mount C-Clamp
The included under-mount C-clamp attaches beneath the desk edge and requires less space underneath the desktop than some conventional attachment arrangements. This can help avoid interference with cable-management systems or structural supports beneath the desk.
Adjustment Range
The mount provides 13 inches (33 cm) of integrated vertical lift. The displays support 180° of tilt and 360° rotation. Pan adjustment is 180° at the base and 360° between the extension and arm. The base rotation stop can be disengaged during installation to increase the base range to 360°.
VESA Compatibility
The 45-518-216 uses VESA FDMI MIS-D mounting and supports 75 x 75 mm and 100 x 100 mm mounting patterns. Verify the monitor's VESA interface and weight before installation.

DC Supplies Product Note
When selecting this exact model, check both monitors individually against the 7–20 lb capacity and confirm 75 x 75 mm or 100 x 100 mm VESA compatibility. The under-mount C-clamp is the defining mounting configuration of the 45-518-216.
