ACA-140 Gas Spring Dual Pole-Mounted Monitor Arm Desk Mount for 17–34 Inch Screens, Adjustable Dual Monitor Mount with Vertical Pole, VESA 75×75 / 100×100, Heavy Duty Clamp & Grommet Mount, Black

• Build a professional and ergonomic dual-monitor workstation with the ACA-140 Gas Spring Dual Pole-Mounted Monitor Arm, designed for users who demand stability, flexibility, and efficient desk organisation.
• Unlike traditional dual monitor arms that rely entirely on articulated joints, the ACA-140 uses a vertical pole-mounted structure to provide enhanced strength and long-term stability. Monitor height is adjusted along the pole, while the gas spring arms deliver smooth, controlled movement for positioning, reducing strain on the mechanism and improving durability.
• Each arm operates independently, allowing precise adjustment of tilt, swivel, rotation, and reach up to 884 mm, making it easy to customise your setup for productivity or collaboration. Whether you work with spreadsheets, code, creative software, or financial trading platforms, the ACA-140 adapts to your workflow.
• Constructed from premium steel, aluminium, and reinforced plastic, this dual monitor mount securely supports monitors between 17 and 34 inches, including ultrawide and curved displays, with a weight capacity of 2 to 10 kg per screen.
• Installation is straightforward using either the included desk clamp or grommet mounting system, making the ACA-140 an ideal choice for home offices, corporate workstations, and professional environments where stability and organisation matter.
