Frequently Asked Questions

Below you will find a list of the most frequently asked questions for this product. If you need more assistance you can email a rack-install technician, or call us at: 1-888-440-5556

If you drive an SUV or van, probably not. Be sure to measure the total height of the vehicle with the Thule 684 Terrapin installed, and keep that information handy (on the inside of your sun visor is a great place). Running into your garage will, unfortunately, void the box's warranty.

While the weight limit of your roof rack may differ, cargo boxes can hold up to 165 pounds.

As long as your vehicle is equipt with the crossbars (side to side) then all of our cargo boxes will attach directly to the rack. If you have a rear hatch, make sure to measure how much room you have and compare to the box length to make sure the hatch won't hit the box when opening. If you don't have crossbars, you will first need to add those prior to adding in a cargo box.
