Thule Xadapt11 - Adapter Kit for Hull-a-Port Kayak Rack

The Thule Xadapt 11 is an optional kit that makes it possible to use the Thule Hull-a-Port roof mount kayak carriers on Thule AeroBlade aluminum load bars. Xdapat11 includes an adapter plate and T bolts, which allows the mounting clamps to fit inside the top slot on Thule's larger diameter bars. If you have a roof rack with square load bars, you do not need this adapter kit. Manufacturer's part number: XADAPT11
