10CMM (BNT4486 Brake Collar)

Genuine Shimano Brake Collar (part #10CMM) — the brake collar is a component of the centrifugal or magnetic braking system on baitcasting reels that controls spool speed during the cast to prevent backlash. A worn or damaged brake collar reduces braking effectiveness, leading to bird's nests and tangled line on every cast. Cross-references with Shimano part number BNT4486. OEM replacement restores precise cast control and backlash prevention. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
