R & R Tackle’s Stainless Steel Kite Rings 10 Packs provide 10 rounded, high quality stainless steel rings specifically designed for use with the R&R M2 kite clip sets. A more rounded and highly polished finish on each ring allows for less friction on your fishing line passing through the ring. These rings are salt and field-tested. The 7.5mm is a slightly thinner ring than the 9mm and this will affect your release pressure (a clip adjustment will be needed). We recommend that you use the same size ring in the entire spread.Â
