To use rooftop cargo tie-down hook straps, follow these steps:
Identify suitable anchor points on your vehicle's roof rack or roof rails.
Place the cargo on the roof and position it securely.
Open the hook on one end of the strap and attach it to the anchor point.
Pass the strap over the cargo and attach the other hook to the opposite anchor point.
Tighten the straps to secure the cargo tightly and prevent movement.
Double-check the straps for tightness and ensure the cargo is firmly held in place before driving.
