Manufacturer's Part Number:

The Thule Sonic roof top cargo boxes are designed to be a combination of technology and style. The Sonic roof top cargo boxes feature a patented aerodynamic design that greatly reduces drag and road noise, and maximizes trunk or rear hatch clearance for maximum vehicle compatibility. These roof top cargo boxes also feature AcuTight mounting hardware, which produces a loud "clicking" noise when the optimal holding pressure has been achieved with the hardware. Each of the Thule Sonic roof top cargo boxes incorporates SecureLock One-Key locks to ensure the roof top cargo box is properly closed and locked before you travel, giving peace of mind on the road.
