<HTML>Jeff The Schaff 48 A or B are moving pad material. The grommet holes are intended for when you move the piano on its side. My experience with smaller ones are that they are so bulky, that people have a tendency not to put them on. If the piano is being moved often, as in many concert settings, perhaps we need to make special precautions, or do something out of the ordinary. I've never done this, but have thought about it, but has any one ever considered putting some sort of rubber "rope" around the edge of the lid, to protect it from the bumps against the doors? I'm thinking of that stuff you put around doors to keep the weather out. (weather stripping).  If that is nailed to the edge of the lid, it could save it from getting dinged. If it is black, it would blend in with the piano, and I doubt anyone would see it on the stage. I guess it is a trade off. Do you want to see black weather stripping on the edge of the lid, or large white spots, where chunks of wood have been chiseled out? Any thoughts on this. Wim </HTML>
