Overview
The Ergotron 98-741-632 LX Pro 2-Piece Clamp Replacement Kit is a replacement mounting component for compatible Ergotron LX Pro arms equipped with a desk clamp base. It is designed to replace a faulty clamp and restore a secure attachment to the edge of a desk or work surface.
The kit includes a two-piece clamp and attachment hardware for installation. Its modular design allows the clamping mechanism to be replaced without replacing the entire compatible mounting setup.
Key Features
- Replacement clamp assembly: Helps restore a compatible LX Pro desk-mounted arm when its existing clamp is faulty.
- Two-piece design: Includes the clamp assembly and required attachment hardware.
- Durable construction: Manufactured using aluminum and steel components.
- Broad desk-edge range: Designed for work surfaces 10–60 mm thick.
- Modular mounting system: Supports maintenance of compatible LX Pro mounting equipment.
Compatibility
This replacement kit is designed for compatible Ergotron LX Pro arms and desk bases that use the specified two-piece desk clamp. It is not intended for grommet-mounted desk bases, and LX Pro components are not compatible with legacy LX products or other Ergotron product lines unless explicitly specified by the manufacturer.
Some LX Pro large bases use two clamps. Check the requirements of the specific base before ordering to determine how many replacement kits are needed.
Desk and Installation Requirements
The clamp attaches to a desk edge measuring 10–60 mm (0.4–2.4 inches) thick. At least 70 mm (2.8 inches) of clear space is required beneath the work surface so the clamp can be installed without interference from obstacles.
Before installation, verify that the desk base and mounting arm are compatible with this kit and that the desk edge meets the thickness and clearance requirements. Follow the manufacturer's installation instructions to ensure a secure attachment.
Applications
- Replacing a faulty clamp on a compatible LX Pro desk-mounted arm.
- Maintaining monitor-arm installations in office and workstation environments.
- Restoring the desk attachment point without replacing the entire mounting arm.
- Servicing compatible LX Pro standard or large desk-base configurations.
DC Supplies Product Note
Confirm the mounting base before purchase. This kit is for compatible LX Pro systems that use a two-piece desk clamp. It cannot be used with grommet mount desk bases. Measure the desk thickness and check for at least 70 mm of unobstructed space beneath the surface before installation.
