Overview
The Ergotron 98-819-290 LX Pro Standard Base with Low-Profile C-Clamp is a white desktop mounting conversion kit designed for compatible Ergotron LX Pro monitor arms. It allows an arm to be installed at the edge of a desk or work surface without requiring permanent alterations to the desktop.
The low-profile C-clamp design provides a secure mounting point while helping minimize interference with desk cables and structural supports. The kit includes a standard base, a 5-inch pole, a pole collar, and a C-clamp.
Key Features
- Desk-edge installation: Attaches to a compatible work surface without requiring holes to be drilled through the desktop.
- Low-profile C-clamp: Provides a compact mounting footprint designed to reduce interference beneath the desk.
- LX Pro compatibility: Supports selected Ergotron LX Pro monitor arms and mounting configurations.
- Complete base kit: Includes the standard base, 5-inch pole, pole collar, and C-clamp.
- White finish: Coordinates with compatible white LX Pro workstation equipment.
Desk Mounting and Installation
The C-clamp secures the base to the edge of a suitable desk or work surface. This approach allows a compatible monitor arm to be mounted without making permanent changes to the desktop.
The clamp is designed for work surfaces approximately 12–40 mm (0.47–1.57 inches) thick. The area beneath the mounting point must also provide sufficient clearance for the clamp and must be free of obstructions.
Before installation, check the desk thickness, underside clearance, and compatibility of the monitor arm. Follow the manufacturer's installation instructions to ensure the base is securely attached.
Compatibility
The 98-819-290 is part of the Ergotron LX Pro mounting system. Listed compatible equipment includes selected LX Pro Desk Monitor Arms, LX Pro Desk Monitor Arms with Tall Pole, LX Pro Desk Dual Direct Arms, LX Pro Dual Side-by-Side Arms, and LX Pro Wall Monitor Arms that support this base conversion.
Compatibility depends on the specific arm and configuration. Ergotron states that LX Pro components are not compatible with legacy LX products or other product lines. Confirm your exact model before ordering.
Applications
- Converting a compatible LX Pro arm to desk-edge mounting.
- Replacing a damaged or missing compatible base assembly.
- Setting up a monitor workstation without drilling through the desktop.
- Creating a compact mounting arrangement where desk space is limited.
