Ergotron DS100 Clamping Double Pivot Add-on - Dual Monitor Flexibility

In this review of the Ergotron DS100 Clamping Double Pivot Add-on, the bottom line is simple: this is a compact, reliable way to add a flexible monitor joint to a DS Series setup. Designed for users who already own or plan a DeskStand 100 configuration, the add-on brings an extra degree of movement and mounting options while keeping overall stability. The review finds it best suited to light to medium displays up to 22.9 lbs total capacity per arm and offers a clear explanation of what the accessory delivers without overselling its role as an add-on component.

Key Features

• Clamping double pivot: The dual pivot provides a wide range of movement for quick screen repositioning and improved ergonomic placement.
• High compatibility: Works with DS Series DeskStand 100 systems to expand an existing base and accommodate multi-monitor layouts cleanly.
• Solid load capacity: Supports up to 22.9 lbs (10.4 kg), letting it handle most 24' monitors within the specified weight limit for stable support.
• Full motion range: Offers tilt 0 - 180, pan 0 - 180 and rotation 360 for flexible portrait or landscape orientation and wide viewing angles.
• VESA support: Accepts common VESA patterns 75 x 75 and 100 x 100 mm, making it compatible with most modern flat-panel displays that meet those standards.
• Discreet black finish: The black color and compact design keep the setup visually tidy and suited for professional workspaces.

Who It's For

The add-on is aimed at professionals and power users who run multi-monitor DeskStand 100 configurations and need an additional pivoting joint to fine-tune monitor placement. Designers, traders, and developers who benefit from precise screen alignment will appreciate the wide rotation and tilt ranges.

It is not intended as a standalone monitor arm for heavy commercial displays; anyone with screens larger than 24' or weighing more than 22.9 lbs should look for a heavier duty solution or a different arm with higher capacity. Casual single-monitor users may find the add-on unnecessary unless they already have a DS Series base.

Pros & Cons

Pros

• Strong motion range that enables both portrait and landscape orientations with smooth adjustment.
• Good load capacity for most 24' class monitors, supporting stable multi-monitor setups.
• Standard VESA compatibility simplifies mounting and replacement of displays.

Cons

• As an add-on, it requires an existing DS Series DeskStand 100 base and is not a complete stand by itself.
• Capacity is limited to 22.9 lbs, so it will not suit larger or heavier monitors beyond the specified size range.
