The bailout kit is attached to his waist belt with a figure 8 in auto lock mode and also doubles as a lanyard for tasks such as roof work. The 8 in auto lock mode is a trick he picked up during his time doing tree work. It’s a simple and cheap way to rig a bailout kit. As the video shows, to start the descent; you simply pull down on the 8. To stop; let the 8 go. Thank you Chris for this great submission!
