NOTICE:
1. These crossbars are made of high-grade aluminum alloy. When carrying larger items like Kayaks, the size will cause extra wind drag that will add additional pressure/weight on both the kayak and the crossbars. The loads weight is the total of the item and attachment installed as well as the pressure from the wind drag.
2. Please check if the bars were positioned correctly. Thicker edge should face forward. Doing opposite will generate tremendous wind noise.
