Backing Up a Rappel: One of the most important safety systems in my opinion.

• OnTheSharpEnd my demonstration of backing up a rappel
• American Alpine Institute a backing up warning with fast buckle harnesses

• ClimbingLife adding a Z near the rappel device
• Mazamas adding a Z near the rappel but also using your leg loop
• American Alpine Institute adding a Z while using a belay device extension
