Description
This is Factory Cat 20421PS, the brush, 20" .022 grit W/Plate.
It measures 20 inches.
Abrasive grit-impregnated filament at .022 diameter. The grit is bonded into the bristle rather than applied as a coating, so it keeps cutting as the bristle wears down.
Supplied with the mounting plate fitted.
