This crossbar monitor desk mount is designed to support up to three 27-inch displays, creating an ergonomic multi-monitor setup that provides an extensive viewing area for productivity. A built-in handle enables moving all monitors simultaneously, while the spring-assisted arm allows multiple adjustments to suit different ergonomic needs.

Height Adjustment with One Smooth Motion

The spring arm enables toolless height adjustment of up to 13in (330mm) with effortless one-touch motion. The max arm extension is 20.7in (526mm), and the weight capacity is 13.2lb (6kg) per monitor.

Visual Experience

This triple monitor mount features micro height adjustment screws on the VESA plate that enable perfect alignment of all three monitors. This is ideal for bezel-less or slim bezel displays, helping to create a more extensive and seamless viewing area. The outer displays' VESA mounts slide along the crossbar, allowing further adjustments.

Range of Motion

The monitor crossbar allows toolless adjustments of +/-15° horizontal swivel of the outer displays. The monitors' VESA mounts enable +/-10° horizontal swivel, +5/-15° tilt, and 360° screen rotation for portrait or landscape orientations.

Cable Management

To maintain an organized workspace, the adjustable arm features a cable management channel along the underside to keep cables out of sight, reducing clutter and contributing to a tidy setup. A cable clip at the base maintains an organized workspace.
