About this product
Introducing the LX Pro—an evolution of the industry-leading LX design. LX Pro combines everything you love about the LX arm with modern enhancements that further streamline installation and maximize ergonomics. It's bound to become the preferred solution when upgrading a workstation. Experience the perfect blend of style and functionality. An added cover safely routes cords, reducing cable clutter for a sleek look while preventing snags when an arm’s in motion. Engage a built-in stop that limits the extension’s side-to-side motion to help prevent damage to adjacent walls or partitions. Modular construction makes it easy to adapt with accessory add-ons and conversion kits as technology shifts and requirements change. The LX line has been a trusted choice in ergonomic workspace solutions for over 20 years; recognized for its quality engineering, flexibility, and innovative Constant Force lift technology. The new LX Pro carries this legacy forward with a modern design, easier installation, and improved ergonomics. With added adaptability for a wide range of monitor setups, LX Pro continues Ergotron’s commitment to solutions that evolve with changing workplace needs.
