Product Description
Maintaining the vintage precision of your STH fly reel is essential for a flawless day on the water. The STH Latch Spring is a critical internal component responsible for the secure engagement of the spool release mechanism. Over time, original springs can lose tension or corrode, leading to a loose spool or failure of the latch to snap back. This replacement part restores that factory-fresh "click" and ensures your spool remains locked during aggressive runs and heavy casting.

Maintenance & Lubrication Tips
To extend the life of your new latch spring and ensure the smoothest spool release possible, proper lubrication is vital:
-
Cleaning: Before installation, ensure the latch cavity is free of old grit and salt buildup.
-
Oil: We recommend a single drop of Deuthlon Reel Oil on the spring coils. This high-performance oil penetrates the tight tolerances of the spring to prevent micro-friction and provides a superior barrier against moisture.
-
Grease: For the contact points where the latch bar slides against the frame, apply a light coating of Deuthlon Reel Grease. This water-resistant grease stays in place even under heavy use, ensuring the latch mechanism operates quietly and smoothly.
Keep your classic STH reel in peak technical condition with this essential replacement latch spring.
