LiftSync monitor arms fits any monitor that are compatible with 75x75 mm (3×3 inches) or 100x100 mm (4×4 inches) VESA mounts.

- Height adjustments through a 9.2 inch-22.2 inch vertical range
- Forward/backward positioning with our articulating arm design
- 180° swivel and 360° rotate capability
- Free Tilting with a +90°/-85° range
