The Ergotron 24-390-026 WorkFit-A Single LD is an adjustable workstation designed to help transform an existing desk into a flexible sit-stand workspace. Its articulated arm supports one compatible monitor, while the suspended keyboard tray and additional worksurface provide dedicated space for everyday computer tasks.
Finished in polished aluminium and black, this workstation uses Ergotron Constant Force lift technology to make height adjustment smooth and convenient. The monitor and keyboard can move together as you change working positions, and the keyboard tray folds upward when you need more desk space.
Key Features
- Single-monitor support: Designed for one compatible display weighing 5–15 lb (2.3–6.8 kg).
- Sit-stand height adjustment: Provides 20 inches (51 cm) of coordinated monitor and keyboard movement, plus 5 inches (13 cm) of independent monitor height adjustment.
- Suspended keyboard tray: Positions the keyboard below desktop level when needed and folds up to reclaim workspace.
- Flexible screen positioning: Supports up to 30° of monitor tilt, 180° of pan and 360° of rotation.
- Additional worksurface: Provides space for lightweight work essentials such as a phone, tablet or notes.
Flexible Sit-Stand Working
The WorkFit-A Single LD is designed for users who want to alternate between sitting and standing without replacing their existing desk. Its articulated arm allows the monitor and keyboard to move together, helping maintain a consistent workstation arrangement as the height changes.
The arm can be repositioned to suit the task, while the monitor pivot provides additional control over screen angle and orientation. When the workstation is not in use, the keyboard tray can fold upward and the arm can be moved aside to help clear the desktop.
Suspended Keyboard and Worksurface
The suspended keyboard tray can sit below the level of the desktop, providing flexibility when arranging the keyboard and mouse. The tray measures approximately 27.1 × 10.1 inches (68.8 × 25.6 cm).
An additional worksurface measuring approximately 22 × 10 inches (56 × 25.5 cm) provides space for lightweight accessories and work materials. Keep all equipment within the applicable load limits for the complete workstation and its individual components.
Monitor Compatibility
This Single LD configuration is designed for one monitor weighing between 5 and 15 lb (2.3–6.8 kg). Ergotron lists a typical monitor size of up to 27 inches, but screen size alone does not determine compatibility. The monitor must also fall within the weight limit and use a compatible mounting pattern.
The monitor pivot supports VESA MIS-D mounting patterns, including 75 × 75 mm and 100 × 100 mm. Check the monitor's specifications before installation.
Installation and Cable Management
The workstation attaches to a compatible desk using a desk clamp. The package documentation also identifies hardware for optional grommet mounting. Confirm that the desk construction, thickness and mounting area are suitable before installing the workstation.
Integrated cable-management components help keep wiring organised as the monitor and keyboard move. Ensure cables have enough slack for the full range of adjustment and do not become caught in the moving arm.
What's Included
Ergotron's product documentation lists the arm and desk clamp, monitor riser, keyboard-tray support bracket, worksurface, keyboard tray, monitor pivot, hardware for optional grommet mounting, assembly fasteners, Velcro, cable wrap and adjustment tools. Confirm the contents and condition when purchasing remaining or previously owned stock.
