Mounting Arm Ergotron LX One-Stop

The Ergotron LX One-Stop mounting arm is a compact rotation control accessory designed to refine the motion range of Ergotron LX arms. With a lightweight metallic construction and compact dimensions (20 mm H × 230 mm W × 180 mm D), this kit attaches to the LX pole to limit rotation and prevent the arm extension from contacting desk panels, dividers or walls. The One-Stop kit is compatible with stacking one or two units to expand the adjustable stop range, offering a practical way to protect surrounding surfaces and maintain consistent arm positioning.

Advantages

The One-Stop Rotational Control Kit provides adjustable mechanical stops that restrict arm rotation without altering arm performance. Its simple attachment method secures the stop to the pole using two set screws, enabling firm placement and repeatable stops. The low weight and compact form factor make it easy to add to existing LX installations or to store and transport as needed.

Suitable for

• Open-plan offices with desk panels or dividers
• Workstations where wall or furniture contact must be avoided
• Shared desks or hot-desking environments to standardize arm reach
• Professional settings where precise monitor placement and repeatable stops are required

Key specifications

• Material: metallic finish
• Weight: approximately 100 g
• Package dimensions: 20 mm (height) × 230 mm (width) × 180 mm (depth)
• Adjustable stop range when stacked: 0° to 300° (using one or two units)
• Attachment method: pole-mounted with two set screws for secure fixation

How to use

Slide the One-Stop kit onto the LX arm pole at the desired height and orientation, then tighten the two set screws to secure the stop in place. To increase the range of rotation control, stack a second kit above or below the first and secure both units. Adjust positioning and test the arm motion to confirm the extension no longer contacts desk panels, dividers or walls. Follow standard safety practices when working with mounted arms, and ensure screws are tightened to prevent unintended movement.

Usage recommendations

Install the One-Stop kit at the height and angle that match typical arm motion for your workspace; test both single and stacked configurations to find the optimal stop range between 0° and 300°. Periodically check set screw tightness as part of routine maintenance to maintain secure stops and consistent arm behavior.
