Grigri Rappels: Backups and Lockoffs

Описание: Many climbers rappel using a Grigri (or other assisted braking device), which is generally a very reliable device, but it is not primarily designed for rappelling. When stopping on rappel, the stop can be made more secure by taking an additional step to secure the brake strand of the rope. This is especially helpful when the Grigri will be inconsistently weighted - common in tree climbing and low-angle terrain such as using a Grigri for edge protection when setting up a top rope.

3 options are presented here, and have different situations in which they are most applicable, but such a discussion is beyond the scope of this video.
