Professional Dual Arm for Heavy Monitors — Smooth, Stable and Precise
The iiyama DS4002C-B1 is the most capable dual screen mounting arm in the iiyama range — engineered for professional users running two larger, heavier monitors who need smooth, precise and stable positioning throughout the working day. Supporting screens from 24″ to 32″ at up to 12kg each, it handles the full range of iiyama ProLite 24″ and 27″ monitors including ergonomic models, and is equally suited to larger displays that other arms cannot support.
Mechanical Spring System for Smooth, Controlled Movement
The DS4002C-B1 uses a mechanical spring system that provides smooth, consistent and controlled movement when repositioning either monitor. Unlike basic friction-based arms that can stick or slip, the mechanical spring delivers a balanced, damped response that makes height adjustment feel fluid and intentional. This is particularly valuable in busy shared workstations and sit-stand desk environments where frequent repositioning is part of the daily routine.
Bearing Tilt Head — Stable at Every Height
A bearing tilt head on each arm prevents screens from sagging or drifting when the arm height is adjusted — a common issue with lower-quality mounts that can cause screens to tilt forward or backward unexpectedly during repositioning. The bearing mechanism keeps both displays correctly angled throughout the full height adjustment range, so that once you have set your tilt preference, it stays exactly where you left it.
Full 360° Swivel and -45° to +90° Tilt Range
The DS4002C-B1 offers a full 360° swivel for complete horizontal rotation of each screen — turning them to face any direction for content sharing, collaboration or switching between users. The generous -45° to +90° tilt range covers everything from near-vertical standard viewing to an almost flat position for touch, presentation or accessible use cases, making this arm one of the most versatile in its class.
Quick Installation with Detachable VESA Plate
The detachable VESA plate and top-mounted desk installation make the DS4002C-B1 quick and straightforward to set up. Both grommet and clamp attachment hardware are included — clamp for non-permanent installation or grommet for a cleaner through-desk setup. Integrated cable management channels along both arms keep cables from both monitors routed neatly and out of sight.
