There's no need for your kayak to monopolize all the real estate on your roof, at least not when you're carrying it in the Rhino-Rack Folding J-Cradle Kayak Carrier. This handy carrier transports your boat on its side so there's room left to attach a cargo box, bikes, or even another kayak. This fully adjustable carrier features a paddle-carrying attachment and a universal mounting system that works with all crossbar shapes, and it folds down when not in use.
