Heavy Duty Arm for Flat and Curved Displays

The white Atdec AWMS-HX40-H supports flat screens up to 31 lb and curved screens up to 26.5 lb. It provides three points of articulation so the display can be adjusted from a seated position. The built-in 180° arm rotation limiter prevents interference with walls or desk partitions. This mount suits users who need reliable positioning for heavier monitors.

Adjustment Range and Load Limits

The arm extends 23.5" horizontally and 13.5" vertically from the post. Tilt adjusts from -35 to +55° while pan covers ±90°. These ranges define the practical positioning envelope for any attached display. Exceeding the stated weight limits will compromise stability and safety. Buyers who need greater reach or higher load capacity should look for a different mount class.

Installation and Common Issues

The accessory mounts to a compatible 400 post and uses standard VESA patterns for the display. Alignment of the three articulation joints during assembly determines how smoothly the arm moves. Over-tightening the tilt or pan bolts can restrict the intended range of motion. Forgetting to engage the 180° rotation limiter often leads to the arm striking nearby walls or partitions.

Questions about this item

Should I pick the 400 mm post version or a shorter post for my desk setup?

The 400 post provides extra height adjustment range; choose it if your monitor needs to sit higher above the mounting surface.

What does the 31 lb flat-screen capacity mean when I mount my monitor?

It means the arm safely supports flat panels up to 31 lb; curved screens are limited to 26.5 lb because their weight distribution differs.

How far can the ±90° pan and -35 to +55° tilt actually move my screen?

You can swivel the display 90° left or right and tilt it 35° down or 55° up from level, with a built-in 180° rotation stop to avoid wall contact.
