10D2P  (BNT1854  Drag Washer B-1)

Genuine Shimano Drag Washer B-1 (part #10D2P, BNT1854) — Drag Washer B-1 is one of the friction discs in your reel's multi-washer drag stack, helping provide smooth, progressive line release under load to protect light leaders and prevent pulled hooks. Over time, drag washers become glazed or compressed, resulting in jerky, unpredictable drag pressure. Cross-references with Shimano part numbers 10D2P and BNT1854. OEM replacement ensures perfect fit and factory performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
