- Accessory Mounting: To mount accessories such as bike racks, roof boxes, or ski carriers, slide the accessory's T-slot adapter into the top channel of the Wingbar Edge. Follow the accessory's specific instructions for secure attachment.
- Load Capacity: Adhere strictly to the maximum load capacity of 75 kg (165 lbs) for the roof bar system, as well as your vehicle's maximum roof load capacity. Never exceed the lower of these two limits.
- Weight Distribution: Distribute the load evenly across the bars. Place heavier items towards the center of the vehicle and secure all items firmly to prevent shifting during transit.
- Driving Considerations: Be mindful of increased vehicle height and potential changes in handling, especially in crosswinds or when cornering, with a loaded roof rack.
Maintenance
Regular maintenance ensures the longevity and safe operation of your Thule Wingbar Edge Roof Bar system.
- Regular Cleaning: Clean the bars and foot packs periodically with mild soap and water. Avoid harsh chemicals or abrasive cleaners that could damage the finish.
- Check Fasteners: Before each use, especially after initial installation or long journeys, check all fasteners and mounting points to ensure they are securely tightened.
- Inspect for Damage: Routinely inspect the bars, foot packs, and rubber components for any signs of wear, cracks, or damage. Replace any damaged parts immediately.
- Lubrication: If applicable, lubricate moving parts or locks with a silicone-based lubricant to ensure smooth operation.
- Seasonal Storage: If the roof rack is not in use for extended periods, consider removing it and storing it in a dry, protected area to prolong its lifespan.
