Tandem Extension for towing device SK1. A line running in a piping which can be attached with velcros. This line gets connected with the release handle of the towing device. The piping is running up the shoulder-belt of the passenger´s harness and is fixed with the velcros. So the Tandem-pilot has the release handle of the extension directly in front of him, at the passenger´s shoulder. This enables the pilot to release the towing device.
