Manta Racks multi-board mount is specifically designed to store both a surfboard and wakeboard or kneeboard. A quality, through-bolted reinforced fishing rod holder must be used to support the weight of the rack with boards. Your equipment is then secured using a bungee cord that is draped over the boards and locked into a designated notch. Note: It's important to measure the angle of your fishing rod holders to ensure you order the correct multi-board rack. For instance, a 15° rod holder will not work with a 30° Manta Rack. Downloading the Angle Meter App for Android or Apple will help you determine the angle of your fishing rod holders before you purchase a Manta Rack system. | Manta Racks 30deg; Multi-Board Rack For Surfboards/Wakeboards - White | The House
