This type secures the reel by rotating the front grip, and is compatible with the skeleton seat (KSKSS) size 16 and the tight spinning seat (TVSK) size 16.
If you use this as a top ring for Fuji Kogyo KN17 hood nut, it will interfere with the size 17 screw, so please cut the screw before use so that it does not interfere when fixing the reel.
