Made of hardened aluminium. No dangerous rods sticking out. A complete set for each size of tent includes drying rail and suspension straps. For sizes 7 and 9 you can select an extra drying ring in one size smaller. For example, to have two drying rings in a tent-size 7, you need a drying rail set 7 and a drying ring 5. Fastening points are found in all tent models as well as in the inner tents.
