Two different attachment methods for a variety of uses: Loop System: Use the Loop System to create high tension without having to tie a knot to secure awkward objects, secure a load in a vehicle or anywhere else! Use your roof rack like the back of a truck to secure mattresses, ladders, small furniture or sporting goods. Fixed-End System: Use the Fixed-End System to attach the Figure 9 in the middle of the rope to hang a banner, secure a tarp, tie a canoe to the top of your vehicle, or tighten any rope with a fixed anchor point.
