Product Description
in-Nor KT321-02 Spool Assembly | Offshore OFS 8500 Replacement
The Fin-Nor KT321-02 Spool Assembly is a high-performance replacement component designed for the rugged Fin-Nor Offshore (OFS) spinning reel series. Built to handle the immense drag pressures and high-speed runs of big-game saltwater species, this spool is a critical component for maintaining the "MegaDrag" capabilities of your reel.
Constructed from machined aluminum, the KT321-02 ensures a large line capacity and superior heat dissipation during long fights. This assembly includes the spool housing and is designed to interface seamlessly with Fin-Nor's multi-stack drag system.

Recommended Maintenance: Deuthlon Lubrication
To maintain the heavy-duty performance of the Fin-Nor Offshore series, we highly recommend using Deuthlon lubricants during the installation of your new spool.
-
Drag System Protection: Apply Deuthlon Fishing Reel Gear Grease (or a dedicated drag grease) to the internal drag washers. This ensures a smooth, non-jerky drag start-up and prevents water intrusion.
-
Spool Shaft & Clicker: Treat the main shaft and the clicker mechanism with Deuthlon Cast Lube or Semi-Fluid Grease to prevent salt crystallization and ensure a crisp audible click when the fish is running.
Standard greases can wash out or harden in extreme saltwater conditions; Deuthlon provides the long-lasting barrier needed for offshore environments.
