Weeeee! The Thule Roller Coaster may not be quite as much fun as its name suggests, but you'll find you love it all the same when you see how easy it makes loading your kayaks. The Roller Coaster is made up of two cradles and (surprise!) a central roller that keeps your boat's pristine hull from rubbing against the crossbar, eliminating friction as you push the boat onto your roof. Best if coupled with Thule's Set-to-Go cradle [THU0026], the Roller Coaster will endear itself to you in no time. The Roller Coaster is designed to mount to Thule square bars only.
Bottom Line: Save your energy for paddling, not loading your boat.
