PRODUCT DESCRIPTION
Description
Massive Support for the High-Stakes Visionary
Command the ultimate digital workspace with the HX Desk Monitor Arm—the definitive engineering solution for large-format and ultra-wide displays. While standard arms struggle with weight, the HX thrives, utilizing patented Constant Force™ Technology to provide effortless, fingertip adjustment for screens weighing up to 42 lbs (19.1 kg).
Designed for professionals who don't compromise on scale, this arm transforms a massive 49-inch monitor into a weightless, floating interface, reclaiming your desktop and optimizing your ergonomic line-of-sight for maximum strategic output.
High-Performance Executive Features
Industrial Weight Mastery: Specifically engineered to stabilize heavy-weight displays (20–42 lbs) with zero "monitor sag." It is the preferred choice for elite creative studios, financial trading floors, and high-tech command centers.
Constant Force™ Fluid Motion: Adjust your massive screen with a single touch. Our pioneering tension system ensures your monitor stays exactly where you position it through thousands of movements, backed by a 10,000-cycle stress test.
Clean-Line Cable Management: Maintain a professional aesthetic. Cables are routed internally under the arm and through the extension, keeping your "Elite" series desk free of "cord-clutter" and snags.
Architectural Rotation Stop: Protect your office infrastructure. The integrated rotation-stop on the base prevents the arm from swinging into walls or glass partitions, preserving both your art and your environment.
Ultra-Wide Compatibility: Ready for the next generation of hardware. With the addition of the Heavy-Duty Tilt Pivot, this arm becomes the ultimate mounting solution for deep-curved "Super Ultra-Wide" displays.
Sustainability & Certification: Built with environmental integrity, holding BIFMA level® 2 and Clean Air GOLD certifications for a low-impact, high-performance footprint.

Incredible quality compared to the cheap arm I previously had. This thing was rock solid, super simple assembly. It held my LG 45" ultra wide R800 5k2k monitor without any issues.
works great ordered 2
This was fun to assemble. . . .
Needed to get an adapter VESA plate for my LG 42" C2, but it supports the weight of it effortlessly.
Very easy instructions, and very good build quality
This monitor arm is very sturdy and seems to have no trouble with my 43 inch screen. I attached it to an Uplift desk with no issues and it really helps make the whole desk look amazing!
