Product Description

SHIMANO 1072A DRAG WASHER (C-G) (BNT2061)

Power the Drag of Your Heavy-Duty Round Reel

The Shimano 1072A Drag Washer (C-G) (Part No. BNT2061) is a critical friction disc found in the multi-stack drag system of Shimano’s larger round baitcasting reels, specifically the Calcutta 400 series. The "C-G" designation typically refers to the material composition (Carbon/Graphite composite) or its position in the stack (Washer C), designed to withstand the heat and pressure of stopping large freshwater and inshore saltwater fish.

In the Calcutta 400 drag stack, this washer is sandwiched between metal keyed washers and eared washers inside the main drive gear. If your drag feels "jerky" (stick-slip) or max drag pressure has decreased significantly, this washer is likely glazed, cracked, or saturated with oil, requiring replacement to restore smooth performance.

Installation Tip: The Calcutta 400 drag is a "stack."

1. Sequence: Ensure you install the washers in the correct order (typically: Washer -> Metal Key Washer -> Washer -> Metal Eared Washer -> Washer).

2. Grease: If these are Carbon/Graphite washers, applying a light coating of Cal's Universal Drag Grease is highly recommended. This prevents the washers from drying out and cracking, and significantly smooths the drag startup.

3. Cleanliness: Ensure the metal washers (Key Washer and Eared Washer) are completely clean of old sludge before installing the new BNT2061.
