It measures 0.5 inches wide and 50 yards long per roll, with a stem density of 400 stems per square inch and an engaged thickness of 0.23 inches. The fastener closes and reopens reliably for up to 1,000 closure cycles, making it a practical mechanical attachment solution for panels, enclosures, displays, and trim components where screws or permanent adhesives are not practical. Rated for indoor use only, it withstands temperatures up to 120 degrees F.\u003c\/p\u003e\n\u003cp\u003eThis fastener tape is suited for indoor applications across trade, commercial, and light industrial environments. Typical uses include securing access panels, equipment covers, cable routing clips, signage, and mounting components to surfaces that cannot be drilled or welded. It bonds to a range of substrates including acrylic, polycarbonate, ABS, powder-coated paints, polypropylene, and polyethylene. Because the two mating strips lock together under light pressure and release cleanly, it is commonly used where technicians need repeated access to a covered component without tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e400 stems per square inch for consistent, repeatable closure force\u003c\/li\u003e\n  \u003cli\u003eUp to 1,000 open-and-close cycles before performance degrades\u003c\/li\u003e\n  \u003cli\u003eRubber-based adhesive bonds to plastics, powder-coated paints, and low-surface-energy materials including polypropylene and polyethylene\u003c\/li\u003e\n  \u003cli\u003e0.23-inch engaged thickness keeps mated profile low\u003c\/li\u003e\n  \u003cli\u003eTemperature resistance up to 120 degrees F\u003c\/li\u003e\n  \u003cli\u003eBlack polypropylene construction resists moisture and common cleaning agents\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with acrylic, polycarbonate, ABS, powder-coated paint surfaces, polypropylene, and polyethylene substrates in indoor environments.

Allow adequate dwell time after pressing the tape to the substrate before engaging the mating strip under load. This product is for indoor use only and should not be installed in areas subject to direct moisture, UV exposure, or temperatures exceeding the rated maximum. Cut strips to length with scissors or a utility knife before removing the adhesive liner.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SJ3542 Type 170\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 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\u003eEngaged Thickness\u003c\/strong\u003e: 0.23 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Density\u003c\/strong\u003e: 400 stems per square inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClosure Life\u003c\/strong\u003e: 1,000 cycles\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 120 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdhesive Type\u003c\/strong\u003e: Rubber-based\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUse Environment\u003c\/strong\u003e: Indoor only\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.82 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00021200863479\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: 7000048573\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346259542322,"sku":"7000048573","price":909.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310518408.jpg?v=1782075477","url":"https:\/\/voomisupply.com\/products\/3m-7000048573-dual-lock-reclosable-fastener-sj3542-black","provider":"Voomi Supply","version":"1.0","type":"link"}
