Thule’s Foot Packs are the “feet” that attach to your vehicle’s roof and allow you to then add Thule crossbars (also called “loadbars”), plus the Thule bicycle mounts and accessories required to carry all your gear (crossbars, mounts and accessories sold separately). All mount without tools, are vinyl-coated so they can’t damage your 4-wheeler, and are engineered to hold fast under all conditions. They have wide bases for excellent support no matter how many bicycles you carry, and most are sealed from the elements to protect the internal mechanism.
