The flyer swings out and makes a position on the bar such as a Knee Hang. As they return to the platform they let go of the bar and grab the 'catcher' who is standing on the platform uprights in a kind of Korean Cradle position. They come off the bar to stand on the platform.
For safety, the 'catcher' should be secured to the platform with a safety belt to prevent them from falling forwards (as they would be on a regular Korean Cradle).
Thanks to Ted and the team at Circus Arts Australia for providing a video for this page.
