The Ergotron 45-522-216 LX Desk Dual Direct Arm is a white dual-monitor desk mount with an under-mount C-clamp designed for side-by-side displays. It supports two monitors up to 25 inches, with a maximum individual monitor weight of 11 lb (5 kg) and a combined capacity of 22 lb (10 kg).
Overview
The LX Dual Direct Arm uses a low-profile dual-monitor crossbar that allows both displays to be repositioned together while each monitor can be tilted independently. Its under-mount C-clamp attaches beneath the desk edge and requires less space than conventional mounting arrangements.
Dual-Monitor Configuration
The 45-522-216 is designed for two side-by-side monitors. Each display can weigh up to 11 lb (5 kg), provided the combined monitor weight does not exceed 22 lb (10 kg). The supported screen size is up to 25 inches per monitor.
Under-Mount C-Clamp
The included under-mount C-clamp attaches to worksurfaces from 0.5–1.26 inches (1.2–3.2 cm) thick. Its low-profile construction is designed for installations where space beneath the desk edge is limited.
Adjustability
The mount provides up to 13 inches (33 cm) of vertical lift, 30° of total tilt adjustment, 360° of pan, and 360° of monitor rotation. The arm can extend up to 24.3 inches (61.7 cm).

VESA Compatibility

Cable Management
Cable management routes monitor cables beneath the arm and within the extension, helping keep the cable path organized without adding unnecessary bulk around the desk edge.
Applications
The 45-522-216 is suited to dual-monitor workstations where side-by-side positioning, simultaneous monitor movement, and a compact under-desk-edge mounting arrangement are required.
