One more question if I may. Looking at both the 4009 and 4010 dollies, it appears you can run a screw through the vertical part of the dolly into the back (I presume) of the piano. I believe the front-to-back dimension of these dollies is fixed. So the front wheel will stick out some distance from the front of the knee board, the exact amount simply depends on the dimensions of the piano - am I understanding this correctly? I guess it would not be obtrusive because one would install them at the extreme ends of the piano (or I guess just inboard of the OEM casters) - correct?
