Key Features
-
Heritage Performance: Restores the classic "Hardy Click" that has defined fly fishing for generations.
-
Consistent Tension: Tempered steel construction prevents the spring from "softening" over time, ensuring your drag setting remains reliable.
-
Easy Installation: Designed for a simple drop-in fit onto the internal pillars of the Marquis frame.
-
Corrosion Resistance: Finished with a protective coating to withstand the damp environments typical of trout and grayling fishing.
Maintenance & Lubrication
To ensure the longest possible life for your check spring and to prevent wear on the pawl, proper lubrication is vital. We recommend Deuthlon high-performance lubricants:
-
Surface Protection: Apply a very light film of Deuthlon Power Grease to the entire length of the spring. This prevents "fretting" corrosion where the spring contacts the frame pillars.
-
Friction Reduction: Apply a small drop of Deuthlon Reel Gear Oil to the tip of the spring where it contacts the pawl. This ensures a smoother click and reduces mechanical heat during high-speed runs.
