A housing is attached to the lower end of the long item being transported. This housing allows the long item to be pulled by a person or machine without damage to the lower, trailing end of the item at which the housing is attached. In one embodiment, the housing is equipped with a wheel or wheels so that it may roll within minimal frictional resistance while the long item is being transported. In a second embodiment, the housing is shaped like a ski, or equipped with a ski or skis so that it may slide easily over surfaces that a wheel cannot roll over with minimal frictional resistance. In a third embodiment, both the ski shape, and the wheeled design are combined to create a device that can easily traverse any surface.
