The Ergotron 45-478-026 HX Wall Monitor Arm is a polished aluminum wall-mounted monitor arm designed for large, heavy displays. It supports monitors weighing from 20 to 42 lb (9.1 to 19.1 kg) and provides 11.5 inches (29.2 cm) of vertical adjustment for ergonomic positioning.
Overview
The HX Wall Monitor Arm provides a flexible mounting solution for large displays while keeping the work surface clear. Its arm can extend up to 24.8 inches (63 cm) and folds back toward the wall when not in use, making it useful where available workspace is limited.
Display Support and Adjustment
The 45-478-026 is rated for displays from 20 to 42 lb. Ergotron lists a typical LCD size of up to 49 inches, with actual usable screen size dependent on the display's weight and physical characteristics. The arm provides 11.5 inches of lift, 70° backward tilt and 5° forward tilt, 180° base pan, and 360° monitor rotation.
VESA Compatibility
The monitor arm supports VESA FDMI MIS-D mounting patterns including 75 x 75 mm and 100 x 100 mm, with additional support for MIS-E 200 x 100 mm and MIS-F 200 x 200 mm patterns on the HX single-monitor configuration. An optional VESA bracket adaptor is available for larger 400 mm mounting patterns.
Wall Mounting
The HX Wall Monitor Arm attaches directly to sturdy vertical surfaces and can also be used with an Ergotron wall track when the appropriate bracket is selected separately. Installation should be made to a suitable structural mounting surface capable of supporting the display and arm.
