The Keyboard Stand L-2C perfect match for Yamaha Keyboard YPT-220. As the figure shows are three screws on the stand. A look at the bottom of the unit indicates whether these three-point attachment is available on keyboards. The assembly is very simple. The image description could be supplemented in any case with "/ YPT-220". I am convinced that this also applies to further Yamaha keyboards.
In the picture the stand unfortunately shown the back.
