Tapered pin for tower wall attachment

A tapered pin (16) for tower wall attachment is disclosed. The tapered pin includes a taper (22) having a first head (23) and a second head (24), the first head being larger than the second head. The taper pin further includes an internal bore (18a) accessible at least from the second head portion. A system (15) for tower wall attachment and a method of installing the system are also disclosed. In case of using a system comprising pins, the tower wall attachment is much safer than the prior art and no welding is needed, thereby greatly simplifying the fixation process and improving the performance of the tower.
