Product Description

SHIMANO QUICK-FIRE II CLUTCH BAR (BNT3468 / 10P5H)

Restore the fast, one-handed casting capability of your Shimano Calcutta with this genuine Quick-Fire II replacement clutch bar.

The Shimano 10P5H Quick-Fire II Clutch Bar (factory part number BNT3468) is the ergonomic "thumb bar" release lever for the "B-Series" Shimano Calcutta baitcasting reels. Located at the rear of the spool, this component allows anglers to disengage the spool for casting with a simple press of the thumb, the hallmark of the Quick-Fire II system.

If your current clutch bar is cracked, sticking, or has snapped off at the pivot points due to heavy use, this OEM replacement will restore the reel's mechanical integrity and casting ease.

Why Replace Your Clutch Bar?

The clutch bar is the most frequently touched part of a baitcaster. Over thousands of casts, the plastic pivot points can fatigue, or salt buildup can cause the bar to bind against the frame. A crisp, responsive clutch bar is essential for accurate casting and ensures the reel re-engages the drive gear smoothly when you turn the handle.

Tech Tip: If your clutch bar feels "mushy" or doesn't spring back up, check the Clutch Pawl Spring and the Clutch Cam underneath the side plate. Often, replacing the bar and cleaning the underlying mechanism simultaneously provides the best results.
