Description
Clamp-Mounted Four-Monitor Desk Arm
Family: Arms & Mounts Category: Monitor Arms Color: Black
Bring four displays together in a two-by-two layout using one desk-edge attachment. Two manually positioned screen-support pairs help organize a multi-window workspace while leaving the area beneath the screens available for other tasks.
Is This Right for You
For a mostly fixed four-monitor workstation where the desk edge can carry a shared mount. Plan the position of frequently used screens and check whether the upper row can be viewed comfortably from your normal working posture.
Key Benefits
- A single clamp replaces four monitor bases and keeps more desktop space available.
- Each screen pair has manual height positioning with a locking lever on the pole.
- Articulated supports, screen rotation and cable guides help align the displays and organize wiring.
Compatibility and Installation
Fits four compatible 17–30 inch monitors, each up to 10 kg without its original stand, with VESA 75 × 75 or 100 × 100 mm. The clamp fits 20–100 mm desktops. Verify desk structure, edge clearance and the full screen layout before ordering.

Materials and Construction
Aluminum and plastic construction with a central upright and a metal desk-clamp assembly. Protective pads sit at the clamping surfaces. Locking levers hold the two screen-support pairs at their selected heights.
Setup and Everyday Use
- Check desk strength and assemble the padded clamp at a suitable edge. Tighten the fixing securely and leave access below the desktop.
- Position and lock the two screen-support pairs. Attach each monitor using screws suited to its VESA holes and screw depth, supporting the screens during assembly.
- Align screen angles and viewing distance, then route cables with slack. Check every lock and the desk attachment before use and after major adjustments.
Limitations
The complete load acts through one desk attachment, so desktop strength matters as well as thickness. Glass, weak or unsupported edges need an approved mounting solution. Screen housings can restrict side-by-side alignment and rotation. Height changes require supporting the screen pair and resetting its lock; there is no spring-assisted lift.
Package and Mounting Options
Four-monitor arm assembly with a C-clamp, protective pads and cable-management parts. Check monitor screws against the supplied hardware. Monitors and desk are not included.

Frequently Asked Questions
Can I install it without drilling? Yes, using its clamp on a suitable 20–100 mm thick desk edge.
Can all four screens change height independently? Height is set for each screen pair; individual screen mounts adjust angle and orientation.
Will four 30-inch screens always fit? No. Check actual screen dimensions, VESA positions and the available space for the intended layout.
