We believe your monitor setup should grow with you—not hold you back. Whether you’re upgrading to a larger screen or expanding your workstation, your gear should be flexible, powerful, and ready for what’s next.

But most monitor arms aren’t built to handle heavy ultrawide screens or add-on configurations. They wobble, they sag, or they’re locked into static positions that limit your workflow.

The AVLT Monitor Arm Add-On Kit is built to change that. Engineered for screens from 17” to a massive 57” and up to 59.5 lbs, this heavy-duty gas spring arm offers smooth, controlled adjustability with industrial-grade strength. It attaches seamlessly to a compatible 1.38"" pole (35mm) and supports VESA 200x200, 200x100, 100x100, and 75x75 mounting patterns—giving you the freedom to expand without compromise.

With advanced tilt and rotation lock features, integrated cable management, and a clean matte black finish, this add-on arm is made for professionals, creators, and gamers who want more from their space.

What sets it apart:

• Supports large 17” to 57” flat, curved, or ultrawide monitors
