Wel it is really easy to tie in a looped configuration. I am assuming you know how to do this... To use them, usually you need two. 1) attached to you harness (a short one) 2) on ewith foot loops (long one). You baisically attach both to the rope and weight one and slide the other one up the rope. Then weight the other one and slide the unweighted one up.... ince by inch. make sense? is that what you wanted to know?
