Installing a friction saver with a rope already set
I was thinking about this the other day and I don't think I've seen it posted before. There are 1000 videos and guides on how to do the regular throw line bag trick. You started without a friction saver and decide to use one. Don't have to climb all the way there if you didn't use the usual throw line method to start. Needs rope available 4x the distance to the TIP so maybe not useful for long distances but this is useful when you're within 30' without undoing your hitch climber.
Lanyard in and pull slack 2x distance to TIP.
Untie termination knot and pass the end through one side of the friction saver.
Use a sheet bend to pull the termination end over the TIP, holding on to the friction saver.
Untie the sheet bend. If you didn't pull enough slack the end won't make it to you on the other side.
Pass the end through the other ring of the friction saver and pull it up into position.
