The VacuRack SOLO carries either a single canoe, kayak or transports a bike when you’re not paddling. Its small size allows stowage in most canoe or kayak, allowing you to throw it on the vehicle at the bottom of your run. The VacuRack SOLO has (3) 4.5″ cups in the front and (2) 4.5″ cups in the rear. Please remember to always tie the front and rear of load you are hauling safely to the vehicle.
