Single Articulating Spring Monitor Arm [Arctic Edition] — HYDRA1A | Amer Mounts

The HYDRA1A [Arctic Edition] is a single articulating monitor arm with a slim aluminum profile and a white finish, built for workspaces where the display gets adjusted often. An internal coil spring counterbalances your monitor’s weight, and a visible tension indicator makes it quick to dial in the right balance during setup. A quick-release VESA plate simplifies installing and removing the monitor, and a built-in 180° rotation stop keeps the arm from swinging into walls, partitions, or neighbouring screens. Built-in cable management keeps cords along the arm and off the desk. Compatible with flat and curved monitors from 17″ to 34″ and 2 to 9 kg, with both a desk clamp and a grommet base included.

Mechanical spring arm

A mechanical spring arm uses a precisely calibrated internal coil spring to counterbalance the weight of your monitor, keeping it locked in position at whatever height or angle you choose. Once set to match your display’s weight, the spring tension holds firm — providing reliable, consistent support throughout the day. Adjusting your monitor is straightforward: apply gentle pressure in any direction and the arm moves smoothly, then holds its new position without any tools or knobs. It’s a proven, durable mechanism built for everyday dependability, making it the ideal solution for monitor setups where your screen stays in one comfortable position for extended periods.

Tension indicator

A spring arm only performs well when its tension matches the weight of the monitor it carries — too loose and the screen sinks, too tight and it drifts upward. The built-in tension gauge shows the current spring setting at a glance, so you can see which way to adjust instead of guessing through trial and error. Tension is set with the included hex key, and the indicator makes it easy to return to the right setting after swapping to a heavier or lighter display. The result is a faster setup and an arm that holds its position from the first adjustment.

Quick-release plate

The included VESA compatible quick-release plate locks securely onto the arm and detaches with a single motion — no tools, no loose hardware. The plate uses a thumbscrew mechanism that holds your monitor during use but releases when you need to move it without tools. That makes it a practical solution for shared workstations, multi-monitor configurations, or any setup where screens need to relocate frequently. It also simplifies the process of swapping monitors entirely — detach, swap, and reattach without having to readjust the arm. The plate is designed to work without interfering with the arm’s cable routing, so cables can be unplugged and kept nearby during a swap and reconnected immediately on reattachment.

180° rotation stop

The arm includes a built-in mechanical rotation stop that limits horizontal swing to 180° — preventing the arm from travelling past a set boundary and striking an adjacent monitor, partition, or wall. This is a practical feature for multi-monitor workstations where the gap between displays is narrow, or for desks positioned close to a wall where an unrestricted arm would make contact during repositioning. The stop is integrated directly into the arm mechanism, requiring no additional hardware or adjustment. It provides a defined range of motion without limiting everyday usability, while protecting both the equipment and the workspace from accidental impact.

Two mounting options

This mount ships with both a desk clamp and a grommet base included — no choosing at checkout, no separate accessory purchases. The desk clamp accommodates surfaces from 10 to 85 mm thick and installs without any modification to your desk, making it the straightforward choice for most setups. The grommet base passes through an existing desk hole, eliminating the clamp profile entirely for a flush, low-profile installation that keeps the focus on the monitor rather than the mount. Having both options in the box means the right fit for your desk is already accounted for, regardless of your workspace configuration.
