The Ergotron WorkFit-TL Sit-Stand Desktop Workstation, MPN 33-418-085, transforms an existing desk into a flexible workspace that accommodates both sitting and standing. This TAA-compliant model features a black frame, dark grey work surface, and integrated keyboard tray, combining practical functionality with a professional appearance.
Designed for convenient installation, the WorkFit-TL sits directly on a suitable desktop without requiring a permanent desk attachment. Its counterbalanced lifting mechanism provides smooth manual height adjustment, allowing the work surface to move up or down without an electric motor or hand crank.
Key Features
- TAA-compliant configuration: Designed to meet applicable Trade Agreements Act requirements, with assembly in the USA using domestic and foreign components.
- 15-inch height adjustment: Move the workstation between seated and standing positions using the manual hand-brake mechanism.
- Spacious work surface: The 37.5-inch-wide platform provides space for compatible monitors and everyday work equipment.
- Integrated keyboard tray: A 27.5 × 11-inch tray moves in tandem with the main work surface and sits approximately 4.5 inches below it.
- Freestanding desktop installation: The workstation arrives fully assembled and sits directly on a suitable desk without special mounting hardware.
Flexible Sit-Stand Working
The WorkFit-TL offers up to 15 inches (38.1 cm) of vertical adjustment, helping users change working positions throughout the day. Hand-brake levers release the lifting mechanism, allowing the work surface to move smoothly without a motor or crank.
The workstation moves straight up and down within its footprint. The keyboard tray moves together with the main surface, maintaining a consistent relative position as the workstation is raised or lowered.
Spacious Work Surface and Keyboard Tray
The main work surface measures approximately 37.5 × 23 inches (95.3 × 58.4 cm). The integrated keyboard tray measures approximately 27.5 × 11 inches (69.9 × 27.9 cm) and sits 4.5 inches (11.4 cm) below the main surface.
The workstation supports a total load of 10–40 lb (4.5–18.1 kg). Compatible displays can be placed directly on the work surface, or suitable monitor-mount accessories can be used to change the display arrangement. Monitor-mount accessories are sold separately.
