The Sailnovo Rooftop Cargo Carrier can be installed on vehicles with or without a roof rack. Follow these steps for proper installation:
4.1 Prepare the Roof
Place the anti-slip mat on your vehicle's roof where the cargo carrier will sit. This mat helps prevent the carrier from shifting and protects your car's paint.

- Unzip the cargo carrier and place it on the anti-slip mat.
- Load your luggage and other items into the carrier. Distribute the weight evenly.
- Zip up the carrier. Ensure the zipper is fully closed.

4.3 Secure the Carrier to Your Vehicle
The carrier can be secured using either a roof rack or door hooks.
4.3.1 Installation with a Roof Rack
If your vehicle has side rails, cross bars, or a basket-style roof rack, use the provided straps to secure the cargo carrier. Pass the straps through the buckles on the carrier and around your roof rack components, tightening them firmly.
4.3.2 Installation without a Roof Rack (using Door Hooks)
For vehicles without a roof rack, use the provided door hooks. These hooks attach to the door frame of your vehicle.
- Open your car door.
- Pull back the weather stripping around the door frame.
