Main description

ACT AC8340 is a premium ergonomic monitor stand designed for users who work with large, heavy, or curved screens and require maximum flexibility and stability. It supports monitors ranging from approximately 17" to 49" and weighing up to 20 kg, making it suitable for standard office displays, ultrawide monitors, and professional graphic or trading setups.

The gas spring built into the arm provides smooth and effortless height and distance adjustment—the monitor moves with minimal effort and remains stable in the selected position. The three pivot points allow precise positioning: bringing the screen closer or farther away, tilting for an optimal viewing angle, and rotating into portrait mode. This enables users to tailor their workstation to their height, posture, and tasks while reducing strain on the neck, shoulders, and back.

ACT AC8340 is designed for professional use. Its all-metal construction, sturdy column, and robust joints ensure reliable performance even with heavy monitors. The top-mount clamp allows installation from above the desk without the inconvenience of working underneath, while the included desk clamp and grommet options provide flexibility for different desk types. The integrated cable management system routes cables neatly along the arm and column, keeping the workspace clean and organized.

Thanks to its combination of a gas spring mechanism, wide adjustment range, and high load capacity, ACT AC8340 is an excellent choice for office users, home office setups, programmers, designers, traders, and anyone who works daily with a large primary monitor and wants maximum comfort and a professional-looking workspace.
