In a web search for large desk grommets I ran across several sites that advertised a "Flexible Brush Grommet" that looked like a strip of nylon brush mateial. All these sites linked to the same place - a discontinued Rockler product. Rockler does sell a plastic frame with two brush strips inside, but I'm looking for a longer slot - about 16 inches long.
Any ideas for a source of this kind of brush material?
