1.1 Package Contents

Verify that all parts are present:

• Keyboard Tray sections
• C-Clamp mounting hardware

• Instruction manual

1.2 Desk Compatibility Requirements

Before installation, confirm your desk meets the following criteria:

• Minimum Desktop Width: At least 31.3 inches (79.5 cm) to accommodate the tray and clamps.
• Desktop Thickness: Between 0.5 inches (1.27 cm) and 1.49 inches (3.78 cm).
• Clearance: Ensure no obstructions like desk frames, crossbars, or raised/beveled edges prevent proper clamp attachment or tray movement.

1.3 Assembly Steps

1. Assemble the Tray: Connect the two sections of the keyboard tray using the provided connecting plates and screws. Ensure they are securely fastened.
2. Attach C-Clamps: Secure the C-clamp mounting hardware to the designated points on the assembled tray.
3. Mount to Desk: Position the tray under your desk. Tighten the C-clamps firmly to the desk edge. The thicker non-slip pads on the clamps help prevent damage and enhance stability.

2. Operating Instructions

The HUANUO HNKB12B Keyboard Tray is designed for ergonomic comfort and efficient workspace management.

2.1 Ergonomic Use

Slide the tray out to position your keyboard and mouse at an ergonomic height. This helps maintain a 90-degree angle at your elbows, reducing wrist and shoulder strain during long work sessions. The tray features wrist-friendly beveled edges for enhanced comfort.

2.2 Smooth Sliding Mechanism

The tray utilizes upgraded and lubricated metal glide tracks for smooth and consistent motion. To use, gently pull the tray forward. To store, push the tray back under the desk. Built-in limiters hold the tray securely in either the open or closed position, preventing accidental sliding.

2.3 Space Saving

By moving your keyboard and mouse below the desktop surface, the tray helps free up valuable desk space, contributing to a more organized and efficient work area.

3. Maintenance

Regular maintenance ensures the longevity and optimal performance of your keyboard tray.

• Cleaning: Wipe the tray surface and clamps with a soft, damp cloth. Avoid using abrasive cleaners or harsh chemicals, as these can damage the finish.
• Check Clamps: Periodically inspect the C-clamps to ensure they remain tightly secured to your desk. Retighten if necessary.
• Glide Tracks: The metal glide tracks are pre-lubricated. If you notice any stiffness in the sliding mechanism over time, a small amount of silicone-based lubricant can be applied to the tracks.

4. Troubleshooting

If you encounter any issues with your keyboard tray, refer to the following common solutions:

• Tray Not Sliding Smoothly:
  • Check for any obstructions in the glide tracks.
  • Ensure the tray is installed level and the C-clamps are evenly tightened.
  • Clean the tracks and apply a small amount of silicone lubricant if needed.
• Tray Feels Unstable or Wobbly:
  • Verify that both C-clamps are securely tightened to the desk.
  • Confirm your desk thickness is within the recommended range (0.5" to 1.49").
  • Ensure the built-in limiters are engaged when the tray is in the desired position.
• Desk Surface Damage:
  • Ensure the non-slip pads on the C-clamps are correctly positioned between the clamp and the desk surface.
  • Avoid overtightening the C-clamps, which can cause indentations on softer desk materials.
