2 useful things if you don't have enuff friction on a rap are:-
Before starting, if you clip a second biner the same size to the belay loop and also to the running rope loop through the ATC it adds about 20% more friction.
It MUST be the same size biner, and clipped to the belay loop or you get LESS friction.
if you are in the middle of a rap, you can do this for lots of extra friction:-
You could get fancy and use screwgates or double biners
As usual, practice these first to see if they are any use to you |
