This is called a three-hole rope, also called a windproof tent rope. The wind rope is not only windproof, but its most important function is to separate the inner and outer tents of the tent and fill the tent. Once the inner and outer tents are effectively separated, condensation in the outer tent will not wet the sleeping bags and clothing in the inner tent.
How to use the windproof rope: After driving the tent stakes into the ground at a 45-60 degree angle, insert the ring into the stakes. (Note that with this method, you can choose the distance of the tent stakes depending on the ground conditions). Then use the front hand to tighten the front end of the tent rope and the back hand to hold the three-hole slide and push it closer to the end of the tent. Pump as hard as you can, the tighter the better. HASAfter you release your hands, you will find that the entire tent rope is very tight and will not loosen. If it is found to be loose, retighten it using the method above.
