Single Articulating Spring Monitor Arm
Overview
The HYDRA1B-W is a single-monitor articulating spring arm built for desks where space is at a premium. Its top-mount installation method means all hardware sits above the desk surface — no reaching underneath — making setup faster and cleaner than traditional clamp mounts. A mechanical spring arm counterbalances the monitor's weight precisely, keeping height adjustments effortless and holding position without drift. The quick-release VESA plate and detachable joints simplify installation and long-term serviceability. Compatible with flat and curved monitors up to 40" and weights up to 12 kg, with both desk clamp and grommet mounting hardware included.
Key Features
- Clamp — On Side of Desk
- Grommet — Through a Hole in Desk Top
Feature Detail
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.
Top-Mount Install
The clamp is designed to mount entirely from above the desk — no crouching, no moving equipment, no reaching blindly under your workspace to tighten bolts. The clamp is engineered so that every connection point, including final tensioning, is accessible from the top. That makes it a practical choice for corner desks, wall-adjacent setups, and anyone with limited mobility who needs full access to the mount without getting under the desk. It also means the entire installation can be completed by one person, without a second set of hands to manage anything underneath.
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 firmly during use but releases instantly when you need to move it. 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.
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 50 mm thick and installs without any modification to your desk, making it the straightforward choice for most setups. The grommet base routes 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.
