Metal Rings and Triangles are useful for numerous applications. Use on multiple bridle kites such as Parafoil, Flare, and Rokkaku Kites to join the bridles at a single point, where the flying line will be attached. Use for joining the bridle lines on a windsock for hanging. Use the Split Rings for attaching tails through a grommet or loop on a kite. The Split Rings are made from nickel-plated tempered steel. The closed rings are made from aluminum.
