Overview
The Ergotron 98-477-216 Low-Profile Top-Mount C-Clamp is a desktop mounting accessory designed for selected Ergotron LX and MXV monitor arms. It provides an alternative mounting method for compatible arms, with a compact design that attaches from above the desk surface.
Designed for desk edges measuring 12–18 mm (0.47–0.71 inches) thick, this clamp is particularly useful for shallow work surfaces and freestanding sit-stand workstations. Its white finish complements compatible Ergotron mounting equipment while helping maintain a clean, organized workstation.
Key Features
- Low-profile construction: Space-saving design minimizes additional bulk around the desktop mounting point.
- Top-mount installation: Attaches from above the desk surface for a practical mounting arrangement.
- 12–18 mm surface compatibility: Designed for compatible desk edges measuring 0.47–0.71 inches thick.
- Broad arm compatibility: Supports selected Ergotron LX and MXV monitor arm configurations.
- White finish: Coordinates with compatible white Ergotron monitor arms and workstation accessories.
Space-Saving Mounting Design
The low-profile clamp provides an alternative to bulkier desktop mounting arrangements. Its compact form makes it useful where desk space is limited or where a workstation has a relatively shallow surface.
The clamp is designed to attach to the desktop edge while maintaining a secure connection with the compatible mounting arm. Correct installation depends on using a supported arm and a work surface within the specified thickness range.
Installation Requirements
This model is designed for desk surfaces measuring 12–18 mm (0.47–0.71 inches) thick. An open gap of approximately 20 mm (0.78 inches) behind the desk surface is required for installation.
Before ordering, measure the desktop thickness and check the space behind the desk edge. Confirm that the clamp is compatible with the intended monitor arm, and follow the manufacturer's installation instructions.
