How is the RoofBag car top carrier 
fastened to a car without a roof rack?

Back to FAQ
1 - PASS-THROUGH STRAPS - A RoofBag car top carrier intended for a car without a roof rack is shipped with 2 Pass-through Straps that fasten the carrier to the door frame of the car. This attachment is secure.

The straps are 1,000 lbs strong, and the buckles are tested to 365 lbs. Additionally, the straps are thin (0.5 mm) and water-repellent to avoid interference with the door seal or water wicking into the car. See installation diagrams for a car without rack using Pass-through Straps.

2 - STRAPS WITH DOOR HOOKS - An alternate installation method for a car without a rack uses the optional Straps with Door Hooks, which attach to a ridge that 70% of cars have on the top section of the door frame.

Straps with Door Hooks need to be ordered separately. See the Extra Straps section of the Products Page.

If your car does not have the ridge required for the Door Hooks, or if you are not sure, we recommend using the Pass-through Straps that come standard with the RoofBag carrier when you order a carrier for a car Without Rack. Pass-through straps work on any car.
