The HUANUO monitor arm HNSS8 adopts a structure that combines a "gas spring" for smooth angle adjustment and a "pole (vertical column)" to firmly support a high position, achieving a higher viewpoint of up to 62cm, which was insufficient with conventional monitor arms. By being able to set the monitor as high as you want, your posture naturally becomes correct, and work efficiency and comfort are significantly improved! 【All-Direction Free Angle Adjustment】 With an innovative multi-axis design, the screen can be smoothly adjusted in all directions: up 35°, down 85°, left and right 90°, and rotation 360°. The arm can also be extended up to 54cm, and can be easily adjusted to your preferred angle, making the screen easy to see in any posture and reducing eye strain. It maintains concentration and increases work efficiency. 【Spacious and Tidy Desk Area】 This monitor arm has two types of mounting methods: grommet and clamp, to match the desk. Since it does not require a monitor base, you can store documents, keyboards, etc. in the space under the monitor, allowing you to use the desk more widely. 【Product List】 Main unit *1 (mounting parts included), Japanese instruction manual *1.
