The numerous small openings in the mesh significantly increase suction performance, as the sanding dust is removed over a much larger surface area. Made from durable nylon fabric, with silicon carbide grit. Waterproof. Even after intensive use, sanding dust can be easily washed off. Once dried, the sanding grid is ready for use again. Easy attachment of the abrasive to the machine; the open structure eliminates the need for precise positioning.
