This is an aftermarket custom part that allows you to add a drag clicker sound to Daiwa baitcasting reels such as the Tatula 80, Tatula 100, 21 Alphas, and 20 Alphas. Due to the structure of this type of drag clicker, the drag force will be reduced by approximately 0.5kg. If you are not familiar with disassembly, maintenance, or drag grease adjustment, the original performance may not be achieved. Also, it is not a 100% plug-and-play installation, and fine adjustments to the gear position may be necessary. You can use the included black double-sided tape on the gear without using adhesive, but we recommend fixing it with adhesive as it may come off. There are no installation instructions or installation support. Please refer to information on the internet, etc., for the installation method. If you are unsure about the work, we recommend asking an experienced person or a shop. This product is "for those experienced in reel disassembly and customization." It is not recommended for those who are not familiar with disassembling and customizing baitcasting reels. P03899
