Ответ:Depending on the aircraft there are different ways this can be installed. One way, if you have a head bar, you can mount this around a tube above the head bar. Another way is you can drill a hole in the spar and use a triangular fitting (does not come with harness) along with lubing a 3 bar slide (comes with harness) and put everything together. With each aircraft it may be different, so different hardware may need to be purchased depending on the application.
