The Dunbier Drop Down Beach Launcher is an absolute must for boaties heading off the beaten track. By simply pulling the spring pin, the entire assembly rotates and your trailer can be disconnected completely and run on it’s own wheel base. Perfect for launching off the beach, on a river or even off a long shallow ramp where you risk your vehicle being inundated. Plus you get the peace of mind at not only carrying a spare wheel but an entire replacement hub everywhere you go.
