Running 2-3\/4 inches wide and 13 yards long, the roll gives technicians and tradespeople a continuous supply of abrasive that can be torn to length on the bench or at the machine. The 120-grit cut sits in the fine-to-medium range, making it well suited for intermediate stock removal and surface prep before coating or finishing. A C-weight paper backing delivers flexibility for contoured work while maintaining enough body for flat-stock applications. The hook and loop attachment system allows quick disc or pad changes without adhesives.\u003c\/p\u003e\n\u003cp\u003eThis shop roll is commonly used in HVAC fabrication shops, plumbing rough-in work involving copper or galvanized fittings, electrical enclosure prep, and general metal finishing. It performs on hand blocks, pneumatic sanders, and inline tools that accept hook and loop abrasives. The blue ceramic aluminum oxide grain is a self-sharpening abrasive that maintains cut rate longer than conventional aluminum oxide, reducing roll consumption over a full workday. Contractors and shop technicians who regularly prep pipe ends, duct edges, brackets, or panel surfaces will find the 13-yard length practical for sustained use without frequent roll changes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic aluminum oxide abrasive grain for extended cut life and consistent material removal\u003c\/li\u003e\n  \u003cli\u003e120 grit for intermediate stock removal and pre-finish surface prep\u003c\/li\u003e\n  \u003cli\u003e2-3\/4 inches wide x 13 yards long — tears to any required length\u003c\/li\u003e\n  \u003cli\u003eC-weight paper backing balances flexibility and support for flat and contoured surfaces\u003c\/li\u003e\n  \u003cli\u003eHook and loop backing for tool-free pad attachment and quick changes\u003c\/li\u003e\n  \u003cli\u003eBlue color coding aids grit identification in multi-roll shop environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with hook and loop hand blocks, pneumatic inline sanders, and orbital tools that accept 2-3\/4-inch wide abrasive rolls or strips with hook and loop backing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo power-down procedure is required for hand-block use, but ensure all rotating tools are fully stopped before attaching or removing the abrasive. When used on powered sanders, confirm the tool RPM rating does not exceed the abrasive roll's rated speed. Secure loose material and wear appropriate eye and respiratory protection when dry-sanding metal or composite surfaces per OSHA general industry standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoll Width\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoll Length\u003c\/strong\u003e: 13 yards\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Paper with Hook and Loop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.25 inches x 3 inches x 5.13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.06 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100091038\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51539423068466,"sku":"7100091038","price":68.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/051e56dee4058be2cb28d316ead247dd.jpg?v=1785839959","url":"https:\/\/voomisupply.com\/products\/3m-7100091038-shop-roll-120-grit-2-3-4-in-x-13-yd","provider":"Voomi Supply","version":"1.0","type":"link"}
