Built on a heavy-duty X-weight cloth backing with closed-coat construction, it delivers consistent aluminum oxide cutting action across the full belt surface. At 320 grit, it falls in the extra fine grade range, making it well-suited for final-pass surface prep, light stock removal, and finishing work where surface quality matters. The belt measures 3-1\/2 inches wide by 15-1\/2 inches long and weighs 0.3 pounds. It is part of the R228 series and is intended for use on stationary or portable belt sanders by trade professionals and skilled fabricators.\u003c\/p\u003e\u003cp\u003eThis abrasive belt is used in metal fabrication, woodworking, and finishing operations where a controlled, fine surface finish is required. The closed-coat aluminum oxide construction keeps abrasive grain packed tightly across the backing, which maximizes cut consistency on flat and contoured workpieces. Dry operation only. Typical applications include finish sanding of wood components, light deburring of metal parts, and surface conditioning before coating or inspection. It is appropriate for both shop and field use wherever a compatible belt sander is available.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e320 grit extra fine grade for precision finishing and final-pass surface prep\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive material provides consistent cut and durability\u003c\/li\u003e\n\u003cli\u003eClosed-coat construction maximizes grain coverage across the belt surface\u003c\/li\u003e\n\u003cli\u003eX-weight cloth backing resists tearing and flexing under load\u003c\/li\u003e\n\u003cli\u003eDry-use only design maintains abrasive performance throughout belt life\u003c\/li\u003e\n\u003cli\u003ePart of the R228 series for consistent spec across production runs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or consumable belt for belt sanders accepting a 3-1\/2 inch by 15-1\/2 inch abrasive belt configuration.
