Monitor Mount | Height Adjustable | Horizontal or Vertical Setup | Tool-less Assembly

Customize your workspace like never before with this premium desk-mount dual monitor arm. It supports two VESA (75x75, 100x100) monitors, side-by-side or stacked. The full-motion articulating arms with spring-assisted height adjustment let you reposition your monitors with ease.

  • Create a dual-monitor setup, side by side (for up to 30” monitors) or stacked (for up to 24” monitors)
  • Full-motion arms with articulation and spring-assisted height adjustment
  • Easy tool-less assembly, and interchangeable arms for flexible setup

Horizontal or Vertical Setup

Create a dual-monitor setup to suit your needs, using the interchangeable arms with quick-connect assembly.

Create a more comfortable and productive workspace with dual monitors, set up side by side.

In a horizontal setup, the dual-monitor mount supports two monitors from 12” to 30”. It’s ideal for numerous uses including graphic design, photo editing and many others.

The interchangeable arms with quick connect give you the flexibility to set up your dual monitors in a stacked configuration.

As a vertical monitor stand, the dual-monitor arm supports two monitors from 12” to 24”. A stacked setup makes it easy to compare information on two screens without scrolling. Please note:  To support two stacked 24” monitors, the height of each monitor (including the bezel around the display) cannot exceed 14" (35 cm).

Full-Motion Articulating Arms

The adjustable dual monitor arm offers a full range of motion on several axes, letting you tilt, pan and rotate. Switch from landscape to portrait viewing. 

Spring-Assisted Height Adjustment 

Raise or lower your monitors with one smooth motion, using the spring-assisted height adjustment. Adjust the tension to your own preference. 

Durable Construction

With its steel and aluminum construction, the dual monitor mount supports a weight capacity of 19.8 lb. (9 kg) per arm. 

Tool-less Assembly 

The quick slide-and-click connections make the dual-monitor mount easy to assemble. Clamp the monitor mount to the side of your desk or table (using the pre-installed desk clamp) or attach it through a grommet hole.  

The TAA compliant ARMDUAL30 is backed by a 10-year warranty and free lifetime technical support.


  • Improve workstation ergonomics in commercial, business and home-office environments
  • Use a dual-monitor setup for customer service, web design, financial analysis and other uses
