This plate will allow you to mount a korean stick to any japanese mount fightstick.
The quality could have been better as it has very rough edges which could easily scratch a surface.
Also the japanese mount holes are concave/drilled which may cause an issue if you don't have large enough washers for the screws, especially if you want to attach a ground wire on it as well.
If you're using this for a korean stick, don't forget to replace the original mounting plate and NOT screw it on top to avoid changing the stick height.
Overall it's a great product that will allow you to mount virtually any stick to any stick mount.
