Rio's Fly Clips are ultra-fast, easy connection clips that allow anglers to change flies with extreme ease and speed while preventing leaders and tippet sections from becoming too short. Simply tie the appropriate sized clip on to the end of your leader and either twist or clip on your fly. Multiple sizes of clip ensure that there is a clip size suitable for the majority of fly sizes. Twist clips are recommended for larger streamers and Salmon/steelhead patterns; and the Rio Clip for smaller dries, nymphs and soft hackles. This chart gives a guideline of approximate fly size for each clip size.
