Single-arm desk mount for 34-inch displays

This single-arm desk mount supports VESA-compatible monitors from 17 to 34 inches weighing up to 17.6 pounds. It attaches via C-clamp or grommet and includes two USB 3.0 pass-through ports for convenient peripheral connections. The arm frees desk surface while allowing flexible screen positioning.

Check VESA pattern desk thickness and USB header

Verify that your monitor uses a VESA mounting pattern compatible with the detachable plate supplied. Measure your desk thickness to confirm the C-clamp or grommet will fit securely. Ensure your computer has an available internal USB 3.0 header or rear port to connect the arm's pass-through cable.

Mechanical spring arm

The arm extends up to 18.4 inches and provides 17.5 inches of height adjustment using a mechanical spring tensioned to your monitor weight. It swivels and tilts 90 degrees each way plus 90-degree rotation for portrait or landscape orientation. Integrated cable management keeps wiring tidy while the dual USB 3.0 ports bring connectivity to desk level.
