• SMOOTH GAS SPRING HOVERING: Experience zero-gravity screen adjustment. The premium articulating gas spring arm smoothly holds 17" to 32" screens (4.4 to 15.4 lbs). Easily fine-tune the tension to perfectly match your monitor's weight for effortless, one-handed height adjustments.

• ULTIMATE ERGONOMIC FREEDOM: Banish neck and eye strain forever. This full-motion arm extends up to 20.5" outward and 18.25" upward. Features a massive -90° to +85° tilt to combat harsh glare, a ±90° swivel for sharing your screen, and full 360° rotation for quick landscape-to-portrait viewing.

• TWO HEAVY-DUTY DESK MOUNTS: Customize your setup without the hassle. Choose between the robust C-clamp (attaches to the edge of your desk) or the secure grommet base (fits 1.5"-2.36" pre-drilled holes). Both rock-solid systems perfectly fit desk thicknesses ranging from 0.39 to 4 inches.

• UNIVERSAL VESA COMPATIBILITY: Engineered to be the reliable foundation of your professional WFH workstation, gaming setup, or office desk. Confidently supports most flat or curved LED/LCD displays using standard VESA mounting hole patterns of 75x75mm and 100x100mm.

CLUTTER-FREE CABLE MANAGEMENT: Reclaim your valuable desk real estate. The integrated cable management system keeps messy AV and power cords completely hidden along the arm. Includes a step-by-step user manual and an organized hardware kit for a fast, frustration-free installation process.
