Genuine Shimano Click Button (part #104GH) — the click button activates the clicker mechanism on conventional and trolling reels, providing an audible alarm when a fish takes line. Essential for trolling and live-bait fishing when you can't watch every rod. A stuck or broken click button means no audible strike alert, risking missed fish. Cross-references with Shimano part number TLD0054. Compatible with Shimano TLD series reels. OEM replacement ensures reliable clicker engagement.
