The Stopper Knot is very simple to tie and is used at the end of the line as a stopper. It's just like the overhand knot that you use to tie your shoes, but with a second pass around. It is also easier to untie after it has been tightened. The Stopper Knot is used on the shock cord of your R&R hammock quilts, as usual all R&R Hammock gear is rigged before you get it, so you can get outside quickly and start enjoying your hang time in your new R&R Hammock!
