    Our Roof Cargo Carrier is compatible with any vehicle that has crossbars, but always make sure your vehicle model can handle the weight on its roof by checking your manufacturer’s manual.

    Yes, our Roof Cargo Carrier fits square crossbars; you may not need to use the included plastic fixators as some crossbars are thinner than others.

    At this time, our Weatherproof Cargo Bag does not come with compatible locking cores. However, you can explore aftermarket locking mechanisms for added security.

    Unfortunately, not at this time. This model of Weatherproof Rooftop Cargo Rack is only extendable from 43 inches to 64 inches in length, but the 21 inch difference provides flexibility to accommodate a multitude of cargo sizes.

    Our Roof Cargo Racks have a removable middle section which allows you to adjust the size of the basket.
