Marshal Parker is world renowned entrepreneur and innovator who is changing the face of aviation, agriculture and architecture with his designs and unique ideas...
Marshal knew there were code restrictions on the external dimensions for helicopter and aviation hangars. He also knew that to maximize the height internally, a single panel hydraulic door would do the trick efficiently with 70% less moving parts than a bifold door. Marshal needed a hangar for his own helicopter so he carefully sketched the dynamics and schematics of what would be his prototype for today's Hydroswing® door.
