Tarpaulin fasteners are universal. They are ideal, for example, for setting up tents, pavilions, and all types of tarpaulins, as well as pool covers. They can also be used to secure banners. A plastic ball is attached to the elastic band. Simply pass the lower end of the elastic through the loop and wrap it around the ball. The secured item should not be loose, so the elastic band can be cut and adjusted as needed. They allow for multiple uses in tourism, agriculture, home, garden, transportation, vehicles, camping, etc. The complete set includes 10 elastic bands. This set is sufficient for a large mounting area. If you want to ensure that your tarpaulin or other protective covering is securely fastened, this set is perfect for you.
