◆ Handle hole size → 5x8mm, which can be attached to Daiwa and Abu reels! (Since it is a foreign product, adjustment of the hole clearance may be necessary, please understand.) Please note that there may be a product error of 1-2mm due to the foreign manufacturing. ◆ Weight: Approximately 8-9g ◆ Compatible with Daiwa bait reels (Steez, Zillion, Tatula, Ryoga, Millionaire, etc.) and other models with the same specifications. ◆ An adapter for Shimano reels is available for an additional 250 yen. If you wish to purchase one, please comment before purchasing. I will change it to a dedicated listing, so please purchase it after that. ◆ The shaft axis of the knob attachment part is 4mm, so Shimano A type and Daiwa S type can be attached. Regarding the installation of the knob, the size and number of bearings, and the number of shims will vary depending on the knob being installed. Please prepare the necessary sizes and quantities yourself. ※ Bearings etc. are not included. ※ If the knob does not rotate after installation → The rotation of the knob may be stopped by tightening the screw. This can be resolved by loosening the screw, reducing the shims, or changing the bearings to thinner ones. ※ Since I am selling as an individual, I will ship with simple packaging. Thank you for your understanding.
