The Thule Motion-xt Alpine Cargo Box is optimized design for best space efficiency, aerodynamics, and vehicle fit. It is easy to mount thanks to the extra wide PowerClick quick-mount system. The integrated torque indicator clicks when it's properly mounted, ensuring fast and secure fitting. It is easy to open and close in all conditions due to grip-friendly outer handles and supporting lid-lifters. The slideLock system with separate locking and opening functions, automatically locks the lid in place and indicates when the box is closed securely. It ensures you have full trunk access with minimal risk of contact with the cargo box, thanks to its forward position on the vehicle roof.
