HX Monitor Arm for 42 lb Displays

The Ergotron HX arm supports a single monitor or TV weighing up to 42 lbs (19 kg). Its polished aluminum construction provides a sleek profile that frees up desk space. Extension and retraction motion combined with height adjustment enable comfortable viewing positions. This accessory suits users who need flexible positioning for large screens.

Capacity Handles 19 kg Maximum Load

The arm comfortably manages displays up to the rated 42 lbs limit. Heavier panels beyond this weight will exceed the structural capacity and cannot be mounted safely. The design maintains stability throughout the full range of motion when the load stays within specification. Users with displays heavier than 19 kg must select a different mounting solution.

Polished Aluminum Build With Desk Mount

The polished aluminum finish resists wear and fits professional environments. A desk clamp and grommet mount are included for secure attachment to worksurfaces. Cable management channels keep routing tidy along the arm segments. Installers who require wall mounting or through-desk bolt patterns not supplied with this unit will need separate hardware.

Questions about this item

Will the 45-478-026 HX arm hold my existing 42 lb display securely?

Yes, the arm accommodates monitors weighing up to 42 lbs (19 kg) so your display is within the supported range.

How do I confirm the arm moves smoothly after mounting it?

Test the extension, retraction and height adjustment; all motions should glide without resistance and the display should stay exactly where you position it.

Does the 45-478-026 package include the VESA mounting hardware or must I buy it separately?

The box contains the polished aluminium arm and standard mounting hardware; VESA screws for your specific monitor are not included and must be sourced separately.
