The Ergotron 45-502-216 LX Dual Stacking Arm with Under-Mount C-Clamp is a white dual-monitor desk mount designed for vertically stacked displays. Its under-mount C-clamp provides a compact attachment beneath the desk edge, while the LX arms provide independent positioning and adjustment for two compatible monitors.
Overview
The 45-502-216 supports two displays with a combined capacity of up to 40 lb (18.1 kg). Each LCD display can weigh from 7 to 20 lb (3.2 to 9.1 kg). The configuration is intended primarily for stacked displays, with displays up to 24 inches fitting the specified stacking-height requirement.
Dual Stacking Configuration
The two LX arms and extensions position one monitor above the other. For stacked installation, Ergotron specifies that the maximum outside height of each display should be no more than 14 inches (35 cm). Larger displays can be accommodated when positioned side by side rather than stacked.
Under-Mount C-Clamp
The included C-clamp attaches to desk surfaces from 0.5 to 1.26 inches (1.2–3.2 cm) thick. Its under-mount configuration requires less vertical space beneath the desk edge than a conventional attachment and is designed for tighter installations.
Monitor Adjustment
The LX arms provide 13 inches (33 cm) of vertical lift, 75 degrees of tilt, 360 degrees of pan, and 360 degrees of monitor rotation. Integrated cable management routes display cables along the arms.
VESA Compatibility
The 45-502-216 uses VESA FDMI MIS-D mounting and supports 100 x 100 mm and 75 x 75 mm mounting-hole patterns.
Key Features
- Supports two displays up to 24 inches
- 40 lb (18.1 kg) combined display capacity
- 13-inch (33 cm) vertical lift
- Under-mount C-clamp for desk-edge installation
- 75° tilt and 360° pan and rotation
Applications
The 45-502-216 is suited to workstations requiring two vertically stacked displays while preserving usable desk space. The under-mount C-clamp is particularly useful where a lower-profile attachment beneath the desktop is preferred.
DC Supplies Product Note
For stacked installations, check the physical height of each display as well as its weight and VESA pattern. Ergotron specifies a maximum outside display height of 14 inches (35 cm) for the stacking configuration.
