Single-arm mount for 49" displays up to 20 kg

The HYDRA1HDGB monitor arm supports one flat or curved screen weighing up to 20 kg (44 lbs) and measuring up to 49 inches. A detachable VESA plate and top-side installation let you fit the arm without crawling under the desk. Built-in cable routing keeps the workspace tidy. The arm swivels and the VESA plate rotates 360° for flexible viewing angles.

Desk thickness and mounting surface check

Verify that your desktop thickness suits the supplied clamp and that the surface is sturdy enough for the arm's 10.63 lb weight plus the monitor. Ensure a VESA-compatible hole pattern on the back of the display matches the detachable plate. Confirm there is clearance behind the desk for the arm's 16.61 inch width and 8.19 inch depth when fully extended. The package includes both clamp and grommet hardware for either mounting style.

Fixed spring tension and silent articulation

The head-tilting spring mechanism is calibrated for loads up to 20 kg; heavier screens will not stay in position and lighter screens may rise unintentionally. Pivot points use bushings that operate quietly during everyday adjustments. No external power is required and the arm adds no electrical load to the desk. The black finish resists fingerprints and shows minimal wear over time.

Questions about this item

Does the arm ship with both clamp and grommet mounting hardware, or must one be purchased separately?

Both clamp and grommet bases are included in the box, so no extra mounting kit is needed.

How do I decide whether the HYDRA1HDGB will suit my display?

Choose it if your monitor weighs up to 20 kg (44 lbs) and measures no larger than 49 inches diagonally.

What does the 20 kg weight rating mean when the arm is installed on my desk?

It guarantees the arm can hold a monitor up to 20 kg through full swivel, tilt and 360° rotation without sag.
