Simu adjustment cable for T5E and T5 E SP tubular motors

The following Simu tube motors can only be adjusted with this adjustment cable
- Simu T5 E
- Simu T5 E SP
- Simu T6 E
- Simu T6 E SP

As there is too much abuse of returning the adjustment cables after they have been used to adjust the tube motor. We have unfortunately had to decide there January 2019 that these adjustment cables can no longer be returned.
