Product Description
Fin-Nor EA039-01 Release Slider – Santiago ST50 Replacement Part
Product Overview
Maintain the precise drag management of your big game tournament reel with this genuine Fin-Nor EA039-01 Release Slider. Engineered specifically for the heavy-duty Fin-Nor Santiago ST50, this component is a critical part of the lever drag quadrant system.
The release slider works in conjunction with the drag lever buttons to manage the transition between drag settings, specifically the safety stops at the "Strike" position. It ensures the lever does not accidentally slip into "Full" drag or "Free Spool" without deliberate action from the angler. If your drag lever feels jammed, the buttons fail to depress, or the stops are no longer engaging crisp, a worn or corroded release slider may be the issue. Replacing it ensures you maintain total control during the heat of battle with marlin, tuna, and large sharks.
