1. Setup and Installation
This section provides detailed instructions for setting up your BONTEC Under Desk Keyboard Tray. Please review all steps carefully before beginning installation.
1.1 Desk Compatibility
Before purchasing or installing, ensure your desk is compatible with the C-clamp mechanism. This keyboard tray is not compatible with desks that have curved, beveled, or rounded edges, or crossbars/support beams underneath the installation area. The desk must have a flat, unobstructed underside for proper clamp installation.

1.2 Required Desk Dimensions and Clearance
The tray requires specific dimensions underneath your desk to slide in and out smoothly:
- Minimum Width: 25.8 inches
- Minimum Depth: 11.4 inches
The C-clamps can attach to desks up to 1.57 inches thick. Ensure there are no obstructions (like crossbars or support beams) in the required area under your desk.

1.3 Installation Steps (No-Drill)
- Assemble the Tray: The keyboard tray comes in two main pieces that connect. Secure these pieces together according to the included hardware.
- Attach C-Clamps: Secure the C-clamps to the support brackets on the keyboard tray. Ensure they are aligned correctly.
- Position on Desk: Slide the assembled keyboard tray onto the edge of your desk. The protective pads on the clamps prevent scratches.
- Tighten Clamps: Hand-tighten the C-clamps securely until the tray is firmly attached to the desk. No drilling or additional tools are required for this step.

2.2 Weight Capacity and Usage
The tray surface measures 20 inches x 11.8 inches and supports a maximum weight of 11 lbs. It is designed for standard keyboards and mice. Please note:

3. Maintenance
To ensure the longevity and smooth operation of your keyboard tray, follow these simple maintenance guidelines:
- Cleaning: Wipe the tray surface with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish.
- Check Clamps: Periodically check the C-clamps to ensure they remain tightly secured to your desk. Re-tighten if necessary.
- Lubrication: The sliding mechanism is designed for smooth operation. If you notice any stiffness, a small amount of silicone-based lubricant can be applied to the sliders.
4. Troubleshooting
If you encounter any issues with your keyboard tray, please refer to the following common troubleshooting tips:
- Tray is Wobbly: Ensure the C-clamps are fully tightened to the desk. Check that the desk surface is flat and the clamps are not obstructed.
- Tray Not Sliding Smoothly: Inspect the sliding rails for any debris or obstructions. Clean the rails and apply a small amount of silicone lubricant if needed.
- Keyboard/Mouse Not Fitting: Verify the dimensions of your keyboard and mouse against the tray's surface (20 x 11.8 inches) and ensure they are not vertical or split ergonomic types, which may not fit.
