HX Monitor Arm 45-475-216 provides flexibility in the form of height adjustability and extension to your heavy monitors, weighing from 20-42 lbs. Mount the HX arm on your desk, install your heavy monitor and what you have freed up is valuable desk space for your writing material, keyboard, mice and other devices. This arm's 11.5" vertical as well as 23.6" horizontal adjustability not only allows you to position your display to suit your ergonomic preference but it also lets you retract the arm over the base or tuck away the monitor under the shelf or cabinet, when not in use. This feature is especially important in space constrained areas. The display adjustability increases ergonomic comfort by reducing strain on shoulders, neck and eyes.

Higher weight capacity of this arm makes it suitable for healthcare, hospital diagnostic/treatment rooms like radiation, graphic designing and surveillance needs that demand heavy monitors. Modular ability to increase from single monitor setup to triple monitor setup (with a HX Triple Bow Kit sold separately) is a big attraction for these industries too. Available in white, matte black and polished aluminum, this arm looks slick and chic and comes with a ten year warranty.

The HX Monitor Arm is the perfect accessory to add flexibility and superior ergonomics to your monitor or TV. The HX features a new post design, frees up space and allows positioning of your display for greater productivity. Sleek and streamlined, it accommodates large monitors weighing up to 42 lbs (19 kg). Extension/retraction motion and height adjustment capability promote user comfort.


IMPORTANT NOTE - Please note that mounting ultrawide monitors is an evolving field. As new monitors are coming to market all the time, it is not possible to test each and every ultrawide monitor with all the arms that we are offering. However based on the specifications, we believe this arm is compatible with most ultrawide monitors. We recommend that, if and when you purchase this arm, do not discard the original packaging material in case it is needed for a return.
