3.3. Installation Steps
- Identify Front and Rear Bars: The front bar is typically longer (approx. 40.4 inches) and may have a label indicating its position. The rear bar is shorter (approx. 39.2 inches).
- Adjust Crossbar Length: Use the provided tool (e.g., Allen wrench) to adjust the length of the crossbars to fit your vehicle's roof rails. This involves loosening screws, sliding the bar to the desired length, and then tightening the screws securely.
- Position Crossbars: Place the front and rear crossbars onto the vehicle's metal side rails at appropriate distances for even weight distribution and cargo stability.
- Secure Clamps: Loosen the screws on the clamps to allow the inner black slider to extend, facilitating clamping onto the vehicle's side rails. Once positioned correctly, tighten the screws firmly to secure the crossbars in place. Ensure all clamps are tight and the crossbars are stable before use.

4. Operating Instructions
4.1. Load Capacity
The Snailfly Crossbars have a maximum load capacity of 260 LBS (approximately 118 kg). It is critical not to exceed this weight limit to ensure safety and prevent damage to the crossbars or your vehicle.

4.2. Cargo Securing
Always ensure that cargo is securely fastened to the crossbars using appropriate straps, nets, or other securing devices. Distribute weight evenly across the crossbars. Regularly check the security of your cargo and the crossbar attachments during long journeys.
4.3. Driving Considerations
When carrying cargo on the roof, be mindful of increased vehicle height, especially when entering garages, car washes, or low-clearance areas. Adjust driving speed and style to account for the altered center of gravity and increased wind resistance.
5. Maintenance
- Regular Inspection: Periodically inspect the crossbars, clamps, and mounting hardware for any signs of wear, damage, or looseness. Tighten any loose fasteners immediately.
- Cleaning: Clean the crossbars with mild soap and water. Avoid abrasive cleaners or solvents that could damage the black powder coating.
- Storage: If the crossbars are not in use for an extended period, consider removing them and storing them in a dry place to prolong their lifespan.
6. Troubleshooting
- Crossbars Seem Loose: Re-check all mounting screws and ensure they are tightened securely. Verify that the crossbars are correctly seated on the vehicle's metal side rails.
- Excessive Wind Noise: Ensure crossbars are installed correctly and all components are tight. Aerodynamic design minimizes noise, but some noise may occur depending on vehicle speed and cargo.
- Difficulty Adjusting Length: Ensure the adjustment screws are sufficiently loosened before attempting to slide the bar. Clean any debris from the sliding mechanism.
