The innovative mounting brackets allow you to install a rooftop tent or a cargo rack on your vehicle in just a few minutes, half the time of a traditional mounting solution. For a more secure installation, the torque tool emits an audible click to alert you when it is sufficiently tightened. For extra security, the mounting brackets lock the tent at the crossbars. There are no loose parts that can easily be lost in dirt or fall onto the car roof. No lifting of the tent is required for installation. Simply place it in the groove, turn, and tighten. Includes 4 mounting brackets and a torque tool. Compatible with a wide range of Thule roof racks, as well as crossbars from third-party manufacturers (refer to the instruction manual for mounting details).
