Measures 6" diameter X 2" thick. Lower light-off temperature. Engage your draft bypass at 100 lower temperature than with ceramic honeycomb. Steel heats up faster than ceramic; recovers more usable heat from wood smoke. Sharp steel edges cut ash as it goes up the flue. Better air flow, less cleaning maintenance.
