Product Description
Fin-Nor CAF421-01 Spool Assembly | Mega Lite MLS100 Replacement
The Fin-Nor CAF421-01 Spool Assembly is the genuine factory replacement spool for the massive Mega Lite MLS100 spinning reel. Designed for high-capacity saltwater applications, this spool is engineered to manage heavy monofilament and braided lines while providing the surface area necessary for smooth drag performance during long runs.
Constructed from machined aluminum, the CAF421-01 is built to resist the corrosive effects of salt spray and the structural stress of high-tension retrieves. Whether you are surf fishing for sharks or targeting large offshore species, a fresh spool assembly ensures your line lay remains consistent and your drag system operates without hesitation.

Recommended Maintenance: Deuthlon Lubrication
To maximize the lifespan of your MLS100 and maintain "like-new" drag performance, we recommend using Deuthlon high-performance lubricants during assembly:
-
Drag System Maintenance: Apply a thin, even coat of Deuthlon Fishing Reel Gear Grease to the internal drag washers. This specialized formula is designed to withstand the high heat of the MLS100's drag system and prevents "stiction" (jerky line release).
-
Spool Shaft & Clicker: Treat the main spool shaft and the clicker mechanism with Deuthlon Semi-Fluid Grease. This creates a waterproof barrier that resists salt crystallization and ensures the clicker remains crisp and functional.
-
Corrosion Defense: Use Deuthlon Cast Lube on any bearing surfaces within the spool assembly to ensure ultra-low friction and long-term protection against the elements.
Deuthlon lubricants are engineered for high-load saltwater environments, providing superior protection compared to standard marine greases.
