[pianotech] Screens under counterbearing bars

That would surprise me since the screen itself is of nominal thickness.

I always thought their purpose was to serve as a  thicknessing shim, as they
often are not under all of the front duplex bars.

Does anyone know what purpose (if any) those mesh screens serve that are
under the movable counterbearing bars on older Steinways?  Are they just non
skid surfaces, or do they function as some kind of buzz barrier between the
bars and the plate, or something else I haven't thought of?
