◆ Handle hole size → 5x8mm, compatible with Daiwa and Abu reels! (Made overseas, so you may need to adjust the hole clearance. Please understand.) Please note that there may be a product error of 1-2mm due to overseas 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 would like one, please comment before purchasing. I will change it to a dedicated listing, so please purchase it then. ◆ The shaft axis of the knob mounting part is 4mm, so Shimano A type and Daiwa S type knobs can be installed. Regarding knob installation, the size and number of bearings, and the number of shims will vary depending on the knob you install. Please prepare the necessary sizes and numbers yourself. ※ Bearings etc. are not included. ※ If the knob does not rotate after installation → The screw may be tightened too much, stopping the knob from rotating. This can be resolved by loosening the screw, reducing the number of shims, or changing to thinner bearings. ※ I am selling as an individual, so I will ship with simple packaging. Thank you for your understanding.
