The 1.2m ,32mm ID / 35mm OD stainless steel tube has been designed to fit the diameter of the base of most wind turbines and is ready drilled to accept coman wind charger.
The tube can then be adapted to a pole or mounting structure of your choice. Please note: as we have no control over how and where turbines are mounted it is your responsibility to ensure that turbines are mounted on suitable structures and in a responsible fashion. The steel tube is not designed to extend the height of a land tower kit.
