Running 4 inches wide by 36 inches long, this belt carries a 320-grit aluminum oxide abrasive on an X-weight polyester cloth backing. The extra-fine grit rating makes it well suited for final finishing passes, light stock removal, and surface preparation before coating or sealing. The closed-coat density provides consistent scratch patterns across the full working surface. Dry operation only. Licensed trade and industrial users install and replace these belts as part of routine machine maintenance and finishing workflows.\u003c\/p\u003e\n\u003cp\u003eThis belt fits standard 4 x 36 inch belt sander platforms commonly used in metal fabrication shops, woodworking operations, HVAC duct and component fabrication, and general industrial maintenance. The R228 series designation identifies it within the NORTON coated abrasives line. At 320 grit, it is appropriate for smoothing welds, deburring metal edges, and final wood surface conditioning prior to staining or finishing. Dry use only — do not apply coolants or cutting fluids with this belt.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e320 extra-fine grit aluminum oxide abrasive for precision final finishing\u003c\/li\u003e\n  \u003cli\u003eX-weight polyester cloth backing for high tensile strength and flexibility under load\u003c\/li\u003e\n  \u003cli\u003eClosed-coat density delivers uniform scratch pattern and consistent material removal\u003c\/li\u003e\n  \u003cli\u003e4 inches x 36 inches belt size fits standard belt sander platforms\u003c\/li\u003e\n  \u003cli\u003eDry operation only — no coolant or fluid required\u003c\/li\u003e\n  \u003cli\u003eNORTON R228 series coated abrasive construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement coated abrasive belt for belt sanders and finishing machines accepting a 4 inches wide by 36 inches long belt configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eBelt replacement is performed by trained operators or maintenance technicians.
