Why is the shaft of the GTS so long, although I should always place the support in the middle?

The shaft of the GTS Allstar is extra long (21 cm) for the following reasons:

1. The tension cable of the “Cable Suspension” can be attached smoothly on the outside, so it doesn’t touch the carrier beam.
2. In order to achieve as much design freedom as possible, e.g., for inclined trees & triangular constructions
3. So that the tree can grow undisturbed into the thickness – you can push the supports further and further outwards over the years.
