Product Overview
Restore the fishing capability of your offshore spinning reel with the Fin-Nor YT4321-01 Spool Assembly Kit. This genuine factory replacement part is engineered specifically for the Fin-Nor Offshore OFS45 (OFS4500), a model renowned for its durability in demanding saltwater environments.
Constructed from a solid block of machined aluminum, this spool offers the rugged strength needed to withstand heavy line pressure and the corrosive nature of saltwater. It features a deep capacity design, allowing anglers to load ample yardage of braided or monofilament line essential for battling strong coastal and pelagic fish.
As a complete "Assembly Kit," this unit arrives pre-loaded with Fin-Nor’s powerful MegaDrag™ carbon fiber drag system. This means the drag washers and retaining clips are already installed, allowing for a quick, tool-free swap so you can get back to fishing immediately.
