These roof pads are designed to safely secure your kayak to your car roof. Unlike solid J Bars, which require that a roof rack be fitted, these roof pads are a quick and easy way to load a kayak onto any vehicle. However, due to being less heavy duty than traditional bars, we do only suggest them for medium journeys. No tools are required and each set comes complete with all the attachments and straps necessary to attach the pads to your car’s roof and hold the load in place. Detailed instructions are included.
