NB A3 Monitor Arm – Premium Adjustable Monitor Mount
The NB A3 Monitor Arm is designed to improve your computer workstation with a flexible, strong and space-saving monitor mounting solution.
Traditional monitor stands occupy valuable desk space and offer limited positioning options. The NB A3 provides a more flexible alternative by allowing you to mount your monitor directly onto your desk.
Featuring a mechanical constant-force spring adjustment system, the NB A3 Monitor Arm allows you to move your monitor smoothly and position it according to your preferred working arrangement.
Whether you are working in an office, playing games, designing graphics or using your computer at home, this monitor arm provides a convenient way to organise your workspace.

Advanced Mechanical Constant-Force Spring System
One of the most important features of the NB A3 Monitor Arm is its mechanical constant-force spring mechanism.
Unlike traditional gas spring monitor arms, the NB A3 uses a mechanical spring-based adjustment system.
This design provides consistent support when positioning compatible monitors and does not depend on gas pressure inside a cylinder.
The mechanical adjustment system is designed for repeated everyday use and provides convenient monitor height adjustment.
According to the product specifications, its mechanism has undergone testing exceeding 50,000 adjustment cycles.
Supports 17–32 Inch Computer Monitors
The NB A3 Monitor Arm is suitable for compatible computer monitors ranging from 17 inches to 32 inches.
Its flexible mounting design makes it useful for different monitor sizes commonly found in offices and home workstations.
Compatible monitor sizes include:

19-inch monitors.
22-inch monitors.
24-inch monitors.
27-inch monitors.
32-inch monitors.
The supported weight capacity is approximately 2–9 kg.
Always check your monitor’s actual weight rather than relying only on screen size.
Strong and Reliable Monitor Support
The NB A3 Monitor Arm is designed to support compatible monitors weighing between 2 kg and 9 kg.
Its metal-based construction provides a strong mounting structure for everyday workstation applications.
The arm’s spring adjustment system helps maintain the selected monitor position when correctly adjusted for the monitor’s weight.
For safe operation, ensure your monitor falls within the specified weight range and that the desk mounting point is sufficiently strong.
Full-Motion Monitor Adjustment
The NB A3 Monitor Arm provides multiple adjustment options for flexible screen positioning.
You can move your monitor according to your seating position, desk height and viewing requirements.
Its full-motion adjustment features include:
Height adjustment.
Forward and backward movement.

360-degree arm rotation.
Portrait and landscape screen positioning.
These adjustment options make the NB A3 a practical choice for different computer workstation arrangements.
360-Degree Arm Rotation
The NB A3 Monitor Arm features flexible arm rotation that allows users to adjust their monitor position according to their workspace requirements.
You can move the arm to create a comfortable viewing arrangement and reposition the monitor when necessary.
The screen can also be rotated between landscape and portrait orientations, subject to the monitor’s compatibility.
Portrait mode is especially useful for reading documents, programming and viewing long webpages.
Quick-Release VESA Mounting Plate
Another useful feature of the NB A3 Monitor Arm is its quick-release VESA mounting plate.
It supports two common monitor mounting standards:
VESA 75 × 75 mm.
VESA 100 × 100 mm.
The quick-release design makes monitor installation and removal more convenient.
Before purchasing, check that your monitor has compatible VESA mounting holes.
Space-Saving Desk Mount Design
The NB A3 Monitor Arm helps free up valuable desktop space by replacing the traditional monitor base with a desk-mounted support system.
This creates more room for your keyboard, mouse, documents and other computer accessories.
It also gives your workstation a cleaner and more professional appearance.
The space-saving design makes it suitable for:
Office workstations.
Home computer desks.
Gaming setups.
Graphic design workstations.
Programming desks.
Video editing environments.
Business workstations.
Durable Metal Construction
The NB A3 Monitor Arm uses a combination of metal-based structural materials and other components designed for monitor mounting applications.

Built-in Cable Management
Cable management is an important part of creating a clean computer workstation.
The NB A3 Monitor Arm includes hidden cable routing provisions to help organise monitor cables along the arm.
This helps reduce visible cable clutter and keeps the desktop looking neat.
It is particularly useful for professional offices, gaming desks and home workstations.
Easy Desk Installation
The NB A3 Monitor Arm is designed for desktop installation with different mounting options.
Depending on the supplied mounting hardware, installation options include:
Desk Clamp Installation: Attaches the monitor arm securely to a compatible desk edge.
