It delivers 250 stems per square inch and an engaged thickness of 0.23 inches, providing a firm mechanical closure rated for up to 1,000 open-and-close cycles. The strip measures 1.5 inches wide by 50 yards per roll and weighs 7.75 pounds. It is designed for indoor use on a range of substrates and is installed by HVAC technicians, equipment fabricators, electricians, and maintenance professionals who need a reliable, repositionable fastening solution without tools or hardware.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for attaching panels, access covers, wire management components, insulation blankets, and lightweight equipment enclosures in both residential and light commercial applications. It bonds to many common surfaces including acrylic, polycarbonate, ABS, powder-coated paints, and low-surface-energy materials such as polypropylene and polyethylene. The roll format makes it well suited for production-line assembly or field installation where continuous lengths need to be cut to size on the job.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e250 stems per square inch for a strong, repeatable mechanical closure\u003c\/li\u003e\n\u003cli\u003eRated for up to 1,000 open-and-close cycles\u003c\/li\u003e\n\u003cli\u003e0.23-inch engaged thickness for low-profile mating\u003c\/li\u003e\n\u003cli\u003eRubber-based adhesive backing for broad substrate compatibility\u003c\/li\u003e\n\u003cli\u003eCompatible with low-surface-energy plastics including polypropylene and polyethylene\u003c\/li\u003e\n\u003cli\u003eIndoor use; temperature resistance up to 120 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with acrylic, polycarbonate, ABS, powder-coated paints, polypropylene, and polyethylene surfaces in indoor environments.

Cut the fastener to the required length using scissors or a utility knife. Apply firm, even pressure along the full length of the strip after placement to activate the adhesive. No electrical shutoff is required for mechanical fastener installation, but follow any applicable facility or equipment lockout procedures when working on energized enclosures or panels.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Density\u003c\/strong\u003e: 250 stems per square inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngaged Thickness\u003c\/strong\u003e: 0.23 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClosure Life\u003c\/strong\u003e: 1,000 cycles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 50 yards per roll\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdhesive Type\u003c\/strong\u003e: Rubber-based pressure-sensitive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 120 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse Environment\u003c\/strong\u003e: Indoor only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.75 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 7010341003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346294374706,"sku":"7010341003","price":2687.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310516514.jpg?v=1782076617","url":"https:\/\/voomisupply.com\/products\/3m-7010341003-dual-lock-reclosable-fastener-sj3540-black","provider":"Voomi Supply","version":"1.0","type":"link"}
