Boost Work Efficiency with Dual Monitor Support: Featuring a 456mm-high pole, approximately 1.5 times the height of a typical pole-style arm, and an arm extension of 568mm each. The maximum height adjustment range reaches 690mm, stably supporting two 17-49 inch flat or curved monitors simultaneously (weight capacity: 2-20kg/monitor). Ideal for various scenarios such as document creation and data referencing in the office, or displaying game screens and chat windows side-by-side, it enables ideal dual-screen layouts, including stacked vertically or arranged horizontally, to suit your needs. Gas Spring Design - Effortless Adjustment for Large Monitors: Each arm incorporates a high-quality gas spring, providing smooth and light operation even with two 49-inch large screens. Each display can be independently adjusted up and down (+50°/-20°), left and right (±90°), and rotated (±180°). By optimally aligning your line of sight with the screen, it reduces strain on the neck and shoulders during long hours of dual-screen work, creating a less tiring work environment. Two Mounting Methods - Stable Installation: Equipped with two installation methods: clamp-style (compatible with tabletops 12-45mm thick) and grommet-style (compatible with tabletops 12-50mm thick), allowing for easy installation with the included wrench and screws. *Note: Please refrain from using the clamp-style if the tabletop is glass or has an outer frame/unevenness (there is a risk of reduced stability). VESA Standard Compatibility & Neat Wiring: Each arm supports VESA 75x75mm/100x100mm standards, compatible with most combinations of commercially available 17-49 inch monitors (VESA-hole-less monitors require a separate adapter). Equipped with independent cable guides on both arms to neatly store two power cords and HDMI cables. Keeps your desk tidy and allows you to concentrate on your work.
