Hi, When tuning a grand piano, I sometimes lean my arm on the front rim of the piano, and the fallboard will often fall down, or flop back and forth. I got a small clamp ( C style ) from sears, and using felt to keep from scratching the piano, you can clamp the fallboard at the top to the rim of the piano, and presto, no more fallboard flop. Best, Hazen Bannister
