Larry, the other option would be to purchase a keyboard stand that has adjustable arms, or, the less expensive method that I used many years ago was to use a couple inexpensive, rubber, door stops and attach them to the arms with wire ties at the back end of the keyboard stand - worked great for years when I was playing the PSR-500, which had a horrible glare problem.

Hope this helps,

Gary cool
