Our Aluminum Heavy-Duty Gas Spring Monitor Arm fits monitors from 17"~32" and holds up to 8kg/17.6lbs(per screen). Its easy grip handle can position two monitors at the same time with ease - just pull up and down. A larger screen means a bigger risk, and we added a screw behind the arm to prevent you from extending the arm past the rear edge of the desk. Easy-Grip Handle: makes pull-down and placement a snap Lateral Shift Brackets: enable fast alignment Gas Spring: perfectly counterbalances the weight of your monitor Slide-in VESA Plate: for quick attachment and detachment Cable Management: keeps everything organized Two Mounting Options: both desk clamp and grommet are included
