Product Description
Hardy 1552393 Check Spring - St. Aidan
Product Description
Restore the reliable braking power and audible feedback of your classic fly reel with the Hardy 1552393 Check Spring. This genuine replacement component is precision-formed from high-grade tempered spring steel, designed specifically for the Hardy St. Aidan.
As a mid-sized workhorse in the Lightweight series (3 3/4" diameter), the St. Aidan requires a check spring capable of handling stronger runs from sea trout, grilse, or large reservoir trout. This factory-original spring provides the correct tension against the pawl, ensuring your drag adjustment is responsive and the signature "Hardy click" remains crisp. Replacing a fatigued or broken spring is essential for maintaining the mechanical performance and value of your vintage reel.
