I want to add a ring to my truckers hitch instead of making a loop in the line. I want something like in the truckers hitch suspension sticky. I went to the Back Packer and to Half Moon Outfitters. They had very very little in the way of climibing gear. They had descender rings, but they werent rings they were complex figure 8s. Any ideas on where I can buy a ring that will hold my weight? Hardware store?
