The Ergotron 24-391-026 WorkFit-A Single HD is an articulated sit-stand workstation designed for users who need flexible monitor positioning and an adjustable keyboard working height. Its desk-mounted arm allows the monitor and keyboard to move together, making it easier to transition between sitting and standing while retaining the existing desk.
Finished in polished aluminium and black, this configuration supports one compatible heavier monitor and includes a suspended keyboard tray, an additional worksurface, a monitor pivot and the hardware required for assembly. The suspended keyboard design lets the keyboard sit below the desktop when needed and fold away to free up desk space.
Key Features
- Heavy-duty single-monitor support: Designed for one compatible monitor weighing 10–20 lb (4.5–9.1 kg).
- Sit-stand height adjustment: Moves the monitor and keyboard together through 20 inches (51 cm), with an additional 5 inches (13 cm) of independent monitor height adjustment.
- Suspended keyboard tray: Supports flexible keyboard positioning and folds up when the workspace needs to be cleared.
- Flexible screen positioning: Provides up to 30° of tilt, 180° of pan and 360° of monitor rotation.
- Integrated cable management: Helps route cables along the arm for a tidier workstation.
Adaptable Sit-Stand Working
Ergotron's Constant Force lift technology allows the monitor and keyboard to be repositioned together with a smooth adjustment. This arrangement helps users adapt their workstation to different working positions without replacing the desk.
The articulated arm can be moved to suit the workspace, while the monitor pivot offers additional control over screen orientation. When the keyboard is not needed, the tray can fold up and the arm can be moved aside to reclaim desk space.
Monitor Compatibility
The Single HD configuration is intended for one heavier display weighing between 10 and 20 lb (4.5–9.1 kg). The manufacturer's typical monitor-size guidance is up to 30 inches diagonally, although actual compatibility depends on the monitor's weight, dimensions and mounting pattern.
The monitor mount supports standard VESA MIS-D patterns of 75 × 75 mm and 100 × 100 mm. Displays using other mounting patterns may require a separate compatible adapter. Always check the display specifications before installation.
Keyboard Tray and Additional Worksurface
The suspended keyboard arrangement is designed to position the keyboard independently of the desktop surface. The included worksurface provides a convenient area for lightweight work essentials, such as a phone, notes or small accessories.
Observe the manufacturer's load limits for the monitor and other workstation components. Do not exceed the specified monitor weight range, and ensure the desk and mounting point can safely support the complete assembly.
Installation and Cable Management
The WorkFit-A attaches to a compatible desk using the supplied desk-clamp assembly. The product documentation also lists hardware for optional grommet mounting. Select the mounting method that suits the desk construction and follow the manufacturer's installation instructions.
Before installation, check desktop thickness, desk stability, available clearance and cable length. The cables must have enough slack to accommodate the workstation's full movement between sitting and standing positions.
