Weight Capacities- Something to remember when shopping for roof racks or crossbars is how much weight you intend to transport. There are also a few soft-sided cargo carriers on this list that can be placed on your roof without rails you feed the straps through your car doors. Usually, these types of adaptors clamp onto your car by using the space between the top of your car door and roof. Multiple manufacturers have created adapters that allow for innovative mounting options for vehicles that were not made with roof rails. Buying crossbars or a rack from the same manufacturer as the cargo box can help ensure they are compatible.Īlternative Mounting Options- If your car does not have roof rails, have no fear. Some sportier cars come equipped with crossbars for example, some Subaru models are ready for a cargo box right off the lot. This is not to be confused with a full roof rack, as the rails provide a convenient spot to mount crossbars and roof racks.

One factor to consider when buying a rooftop cargo box is rack compatibility. What to Look for in a Rooftop Cargo Box Mounting on roof racks, roof rails and crossbars
