Overview
The Ergotron LX Pro Dual Side-by-Side Monitor Arm, part number 45-686-293, is a dark grey desk-mounted arm designed to support two monitors in a side-by-side configuration. The LX Pro design provides independent positioning of both displays and uses Constant Force lift-and-pivot technology for monitor adjustment. The configuration uses a compact two-piece desk clamp and a 5.3-inch (13.5 cm) pole.
Monitor Support and Adjustment
The arm supports two displays up to 27 inches, with an individual monitor capacity of 4–20 lb (1.8–9 kg) and a total capacity of 40 lb (18.1 kg). Each display can be adjusted through 13 inches (33 cm) of lift, 85 degrees of tilt, 180 degrees of monitor pan, and 360 degrees of rotation.
Mounting and Compatibility
The two-piece desk clamp is designed for surfaces from 0.4 to 2.4 inches (10 to 60 mm) thick. The monitor pivots use the MIS-D VESA mounting pattern, supporting 75 x 75 mm and 100 x 100 mm mounting holes. The arms provide up to 25 inches (64 cm) of extension.
