Product Description
Fin-Nor DAF321-01 Spool Assembly | Offshore OFS 10500 Replacement
Maximize the line capacity and extreme drag performance of your saltwater arsenal with the Fin-Nor DAF321-01 Spool Assembly. This is the genuine factory replacement spool for the massive 10500-size Offshore (OFS) series—the largest and most powerful reel in the Fin-Nor spinning lineup.
Designed for the most demanding big-game applications, including drone fishing, deep-sea trolling, and land-based shark fishing, this spool is a core component of the MegaDrag system. It features a heavy-duty, machined aluminum construction with a high-capacity deep-spool design to hold the hundreds of yards of heavy braid or monofilament needed to stop pelagic giants.

Recommended Maintenance: Deuthlon Lubrication
To maintain the 60lb stopping power of your OFS 10500 and ensure your spool remains protected in extreme saltwater conditions, we highly recommend using Deuthlon lubricants:
-
MegaDrag System: Apply a light coat of Deuthlon Fishing Reel Gear Grease to the carbon fiber drag washers. This specialized formula prevents "stiction" and provides a superior heat-resistant barrier that standard greases cannot match.
-
Spool Shaft & Clicker: Use Deuthlon Semi-Fluid Grease on the spool clicker and the interface where the spool sits on the main shaft. This prevents salt crystallization and ensures the audible clicker stays loud and functional.
Deuthlon’s synthetic technology is specifically designed for high-torque, heavy-cranking reels like the Fin-Nor Offshore, offering maximum protection against the elements.
