Overview
The Ergotron Interactive Arm LD, part number 45-361-026, is a wall-mounted articulating arm designed to support compatible LCD monitors, televisions, and interactive displays. Finished in polished aluminum, it allows users to reposition a mounted screen by lifting, swinging, extending, or turning the display.
The arm is designed for environments where a screen needs to move between viewing and interaction positions. Its articulated construction supports adjustable display placement without requiring the wall mount itself to be relocated.
Adjustment and Movement
Ergotron's Constant Force technology enables light-touch positioning. The arm provides up to 20 inches (50.8 cm) of vertical adjustment and extends approximately 24 inches (61 cm) from the wall. When retracted, it sits approximately 5.5 inches (14 cm) from the wall.
The gravity pivot allows the display to tilt, while a locking knob can secure the selected tilt position. A post-installation leveling adjustment of plus or minus 5 degrees helps correct the screen's alignment after mounting.
Display Compatibility
The Interactive Arm LD supports displays up to 42 inches, subject to a maximum supported display weight of 25 lb (11.3 kg). The manufacturer's stated load range is 7–25 lb (3.2–11.3 kg).
Display size alone does not establish compatibility. Before installation, confirm the monitor or television's weight, mounting-hole pattern, and suitability for the arm's VESA mounting interface.
Mounting and Installation
This model is designed for wall installation. The documented package contents include the articulating arm, wall mount bracket, VESA adapter brackets, and a hardware kit.
Installation must use a suitable wall structure and mounting method. The appropriate fasteners and installation procedure depend on the wall construction. Review the manufacturer's installation instructions before mounting the display.
Key Features
- Constant Force technology: Supports smooth, light-touch display repositioning.
- Extended reach: Extends approximately 24 inches from the wall and retracts close to the mounting surface.

Applications
The arm can be used for compatible displays in meeting rooms, collaborative work areas, educational spaces, interactive presentation environments, and other installations where a wall-mounted screen needs to move between viewing positions.
DC Supplies Product Note
Check both display weight and mounting compatibility before ordering. The 42-inch maximum screen size is not a guarantee that every display of that size will fit. The display must also remain within the arm's supported weight range, and the wall structure must be suitable for the mounting arrangement.
