It delivers 250 stems per square inch and an engaged thickness of 0.23 inches, producing a secure mechanical closure rated for up to 1,000 open-and-close cycles. The roll measures 3\/4 inch wide by 50 yards long and weighs 2.75 pounds. Designed for indoor applications, it handles temperatures up to 120 degrees F. Technicians and installers use this tape to create tool-free, reclosable bonds on panels, covers, and assemblies where conventional fasteners are impractical.\u003c\/p\u003e\u003cp\u003eThis fastener tape is suited for residential and light commercial indoor installations where a clean, removable, and repeatable attachment is required. It bonds reliably to many rigid plastics including acrylic, polycarbonate, and ABS, as well as powder-coated paint surfaces and low-surface-energy materials such as polypropylene and polyethylene. Common applications include securing access panels, wire management covers, HVAC cabinet liners, and equipment enclosures where repeated service access is expected.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e250 stems per square inch for consistent, repeatable mechanical closure\u003c\/li\u003e\n\u003cli\u003eRated for 1,000 closure cycles without significant performance loss\u003c\/li\u003e\n\u003cli\u003e0.23-inch engaged thickness provides positive tactile engagement\u003c\/li\u003e\n\u003cli\u003eRubber-based adhesive backing adheres to a wide range of plastic and painted surfaces\u003c\/li\u003e\n\u003cli\u003eLow-surface-energy compatibility covers polypropylene and polyethylene substrates\u003c\/li\u003e\n\u003cli\u003eIndoor-rated with temperature resistance up to 120 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eBonds to acrylic, polycarbonate, ABS, powder-coated paints, polypropylene, and polyethylene surfaces. Designed for indoor use only. Confirm surface compatibility with a test bond before full installation on critical assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface preparation is critical — clean and dry all bonding surfaces thoroughly before applying the adhesive backing, as oils, dust, and moisture will reduce adhesion. Apply firm, even pressure along the full length of the tape after positioning to maximize initial bond strength. Because this is an indoor-only product, do not install in locations exposed to direct moisture, outdoor conditions, or temperatures above 120 degrees F. No special tools are required, but allow adequate dwell time after application before loading the joint.\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: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 50 yards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdhesive Type\u003c\/strong\u003e: Rubber-based\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Resistance\u003c\/strong\u003e: Up to 120 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication Environment\u003c\/strong\u003e: Indoor use only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.75 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: 7100016686\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344660169010,"sku":"7100016686","price":681.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310528103.jpg?v=1782039467","url":"https:\/\/voomisupply.com\/products\/3m-7100016686-dual-lock-reclosable-fastener-sj3540-black","provider":"Voomi Supply","version":"1.0","type":"link"}
