Rio Trout Leaders 9ft – 7X -.004" – 2.4lb – 1 Pack – Knotless – NOS
The Rio Trout Leaders 9ft – 7X – .004″ – 2.4lb – 1 Pack – Knotless – NOS appears to be a specialized tapered leader designed for trout fishing. Here’s a breakdown of its features:
Key Specifications:
– Length: 9 feet – Ideal for delicate presentations in small to medium-sized streams.

– Tippet Size: 7X (extra fine) – Best for tiny dry flies, midges, or spooky trout in clear water.
– Diameter: 0.004″ – Ultra-thin for minimal visibility.
– Breaking Strength: 2.4 lbs – Very light, requiring finesse when playing fish.
– Construction: Knotless tapered – Smooth transition from butt to tippet for better turnover.
– Condition: NOS (New Old Stock) – Likely unused, older inventory (possibly vintage/discontinued).
Best Use Cases:
✔ Small dry flies (e.g., size 18-24)
✔ Technical spring creeks or clear tailwaters
✔ Selective trout in low-pressure waters
✔ Euro nymphing (as a light tippet extension)
Considerations:
⚠ 2.4 lb test is fragile – Best for experienced anglers who can manage light tippets.
⚠ 7X is not ideal for windy conditions or heavy flies – May collapse or break easily.
⚠ NOS may mean limited availability – Check for brittleness if stored for years.
Alternatives (if unavailable):
– Rio Powerflex Trout Leaders (similar taper, newer stock)
– TroutHunter Fluorocarbon Leaders (better abrasion resistance)
– Hand-tied leaders with 7X tippet (customizable)
