Overview
The Ergotron 98-820-293 LX Pro Standard Base with Low-Profile C-Clamp and Tall Pole is a mounting conversion kit for compatible Ergotron LX Pro monitor arms. It allows an arm to be installed at the edge of a desk without drilling or permanently altering the desktop. The low-profile C-clamp creates a streamlined mounting point, while the included 12-inch pole provides the required support height for compatible configurations.
Finished in dark grey, this mounting base is designed for professional workstations, home offices, and other desk-based display environments. It supports a maximum load of 44 lb (20 kg), subject to the requirements and limitations of the compatible monitor arm.
Key Features
- Low-profile C-clamp mounting: Attaches to the edge of a compatible desk without requiring holes in the desktop.
- Tall 12-inch pole: Provides a mounting post for supported LX Pro monitor arm configurations.
- 44 lb load capacity: Supports a maximum load of 44 lb (20 kg).
- Complete conversion kit: Includes the standard base, 12-inch pole, pole collar, and C-clamp.
- Dark grey finish: Coordinates with compatible dark grey LX Pro equipment.
Mounting and Installation
The C-clamp attaches to a desk edge with a thickness of 12–40 mm (0.47–1.57 inches). Allow approximately 38 mm (1.5 inches) of clear space beneath the desktop for the clamp, and check for obstructions such as structural supports, cable trays, or other desk hardware before installation.
Confirm that the desk surface and selected monitor arm meet the manufacturer's installation and load requirements. Follow the Ergotron installation documentation for the appropriate assembly and tightening procedure.
Compatibility
This conversion kit is designed for selected Ergotron LX Pro monitor arms, including compatible desk monitor arms, tall-pole arms, dual-stacking arms, dual-direct arms, dual side-by-side arms, and wall monitor arms. Confirm the exact arm model before ordering. LX Pro components are not compatible with legacy Ergotron LX products or other product lines.
The C-clamp base is not intended for expanding a setup to three or four monitors; those configurations require a suitable large base rather than this C-clamp model.
Applications
- Converting a compatible LX Pro arm to desk-edge mounting.
- Refreshing or reconfiguring an existing LX Pro workstation.
- Setting up professional office and home-office display stations.
- Mounting compatible display arms where drilling into the desktop is not desired.
DC Supplies Product Note
Before purchasing, verify the monitor arm's exact model number, the desk-edge thickness, the clearance beneath the desk, and the total supported load. This product is a mounting base conversion kit, not a complete monitor arm or display.
