The best solution for almost all types of aircraft maintenance work is tying off to a permanent overhead engineered system. There are two basic types of permanent overhead systems: a cable system and a horizontal rail system. A cable system is strung horizontally across hangar roof beams and supported by intermediate brackets spaced evenly to help distribute the forces of a fall.
