StarTech 3M1A3SG-MONITOR-ARM Triple Monitor Mount with One Touch Adjustment

Overview :

The StarTech 3M1A3SG-MONITOR-ARM is a commercial-grade triple-display mounting solution engineered for high-density professional environments. It is utilized by trading floor operators, control center engineers, and software developers who require a synchronized, seamless panoramic viewing area across three 27-inch displays.

Technically, the unit features a spring-assisted mechanical arm and a crossbar assembly that supports a combined load of 39.6 lb (18 kg). It integrates micro-height adjustment screws on each VESA plate, allowing engineers to physically align displays to the millimeter—a critical requirement for bezel-less or slim-bezel deployments.

Deployment is versatile, supporting either C-clamp or grommet mounting on desks up to 3.1 inches (80 mm) thick. It includes a 180° rotation stop mechanism to prevent the arm from over-extending into cubicle walls or glass partitions. This mount is not recommended for curved or ultra-wide displays that exceed the specified 27-inch per-display limit.

Key Features :

• Spring-assisted arm provides 13-inch toolless one-touch height adjustment.

• Synchronized crossbar handle allows simultaneous movement of all displays.

• Micro-adjustment screws on VESA plates enable perfect horizontal alignment.

• Integrated cable management channels reduce clutter in high-density desks.

• Adjustable tension mechanism scales to support displays from 17″ to 27″.
