◆ Handle hole size → 5x8mm, which can be attached to Daiwa and Abu reels, but becomes 4x7mm by attaching a Shimano conversion adapter. ◆ Compatible with Daiwa bait reels (Steez, Zillion, Tatula, Ryoga, Millionaire, etc.) and other models with the same specifications. ◆ Compatible with Shimano bait reels (Metanium, Aldebaran, Scorpion, Exsence, Calcutta Conquest, Antares, SLX, etc.) and other models with the same specifications. ◆ Since this is a foreign-made product, some adjustment of the hole clearance may be necessary. Please understand. ◆ Please note that there may be a product error of 1-2mm due to being a foreign-made product. ◆ The shaft axis of the knob mounting part is 4mm, so Shimano A type and Daiwa S type can be installed. Regarding the installation of the knob, the size and number of bearings, the number of shims, etc., 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 an individual seller, I will ship with simple packaging. Thank you for your understanding.
