This custom part allows for brake adjustment with a single screw without opening the side cover during fishing, unlike the fixed type often found in off-the-shelf products. ■ Features of this product Reaching the Limit of Distance: From centrifugal brakes using friction to contactless control using magnetic force. Supports ultra-long casting with lower resistance spool rotation (can also be used in conjunction with centrifugal brakes). Stepless Adjustment on Site: Adjust the brake strength in millimeter increments to suit the situation by tightening the screw. You can quickly find the best setting. No Modification of the Reel Body Required: Installs using existing holes and the frame, so there is no need to cut or drill into your precious reel. Line Alarm Compatible: Although the operability will change slightly due to some interference, the line alarm function can be used even with this product installed. ■ About Compatible Models Models using part list number: 44685.
