The AlzaErgo Arm D135B Mechanic dual-monitor mount combines a load capacity of up to 11kg (10kg for curved monitors) per arm with a modern design—you can easily mount most flat and curved monitors with screen sizes ranging from 17" to 35". The robust construction and durable mechanical springs ensure maximum stability and a long service life, while also allowing for smooth, almost effortless adjustment of the screen position. Another benefit is rotation restriction via a lock in the base, ensuring the mount won’t extend beyond the edge of the desk or bump into the wall behind it. Quick-release (removable) VESA plates significantly simplify installation, allowing you to mount monitors in an instant. With a wide range of motion, including tilt, swivel, and rotation, and the option to mount either on the edge of the desk or through the desktop, the mount adapts to any workspace and the user’s individual needs. The mount’s modern design fits equally well in a professional office or a home workspace.


Thanks to the flexible design with durable mechanical springs, the monitors can be adjusted exactly as needed to maximize the customization of your workspace. The arms of the AlzaErgo Arm D135B Mechanic offer a truly wide range of motion—you can always fine-tune the position of the screens according to your preferences and ergonomic requirements. The screens can be moved closer or farther away, adjusted for height (218–469mm), tilted (+75° to -45°), swivelled sideways (+90° to -90°), and rotated (+180° to -180°). Of course, you can also rotate themonitors vertically (pivot). This makes it easy to set the optimal viewing angle for both work and content viewing.

The AlzaErgo Arm D135B Mechanic monitor arm features an improved one-way bearing mechanism for easy monitor tilting, ensuring a highly comfortable user experience. Upward movement is light and smooth, while tilting downward requires slight pressure, allowing for greater control and contributing to more precise adjustments. A practical cable management system also helps organize cables so that the workspace remains clean and uncluttered.

There are two mounting options: either directly to the edge of the table using a clamp (10–50mm), or through a hole in the tabletop (10–50mm). Another advantage is top-down installation, which eliminates the need for awkward screwing under the desk. Then all you need to do is attach the joints, tighten a few screws, and the mount is ready to use. The mounting kit is included in the package, and if mounting through the tabletop, you will only need a (cordless) drill. The combination of a durable construction, modern design, and maximum movementflexibility makes the AlzaErgo Arm D135B Mechanic mount a top-notch solution for anyone who wants to keep their monitors in the ideal position at all times. You can view the installation process and the mount’s adjustment options in the video below.

Another major advantage of the AlzaErgo Arm D135B Mechanic mount is the ability to adjust the rotation range at the base using a lock, reducing it from the original ±180° to ±90°. This solution allows you to adjust the range of motion of the arms to suit your specific workspace. You’ll appreciate this feature, for example, when you want to prevent the arms from extending beyond the edge of the desk, bumping into the wall behind the desk, or intruding into the workspace of a colleague sitting across from you. It thus contributes not only to greatersafety but also to the long-term stability of the entire workstation.

The mount is equipped with universal VESA 75×75 and 100×100mm mounts, which cover most standard monitors on the market. Thanks to the removable VESA plates, installation is extremely convenient—first attach the plate to the monitor, then simply mount the entire assembly onto the arm of the AlzaErgo Arm D135B Mechanic. This system significantly simplifies installation and any future adjustments to your workspace. It is also safer, as it minimizes the risk of the monitor accidentally falling.

For optimal performance of the AlzaErgo Arm D135B Mechanic mount, it is important to adjust the spring tension. Adjustment is performed using an Allen wrench directly on the arms. Turning in the "+" direction increases spring tension, while turning in the "−" direction decreases it, allowing you to precisely adjust the resistance to the weight of the monitors. Another practical feature is the spring tension indicators, which are clearly visible on the arms and allow for a quick check of the current settings. With proper adjustment, the monitors willremain stable in the desired position, and their height and position can be adjusted smoothly and effortlessly. More detailed information on the settings can also be found in the included manual.
