Product Description
Hardy 1540723 Regulator Wire - Flyweight, Featherweight, LRH
Product Description
Restore the precise tension adjustment of your classic fly reel with the Hardy 1540723 Regulator Wire. This genuine replacement component is the critical link in the rim-mounted check mechanism, transferring the movement of the regulator button to the check spring.
Over time, original regulator wires can bend, corrode, or fatigue, resulting in a loss of drag range or a "soft" click. Installing this factory-specification wire ensures your reel's tension adjuster operates smoothly and holds its setting, preserving the signature performance of your Hardy Lightweight series reel.

Maintenance Recommendation
To ensure the regulator wire slides smoothly against the cam and spring without binding, proper lubrication is essential. We recommend using Deuthlon Reel Grease or Oil. Their advanced formula provides long-lasting protection against corrosion and reduces wear on metal-to-metal contact points within the check mechanism.
