Each strip features a polypropylene mushroom-stem profile backed by a rubber-based pressure-sensitive adhesive. The stem density is 400 stems per square inch, and the engaged thickness when mated is 0.23 inches. Rated for up to 1,000 open-and-close cycles, this fastener is designed for indoor applications where a durable, tool-free reclosable attachment is required. It ships as a 2-inch-wide roll, 50 yards in length.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for residential and commercial interior applications where mechanical fastening, panel attachment, or component mounting is needed without hardware. It bonds well to a range of substrates including acrylic, polycarbonate, ABS, powder-coated paints, and low surface energy materials such as polypropylene and polyethylene. Typical use cases include securing access panels, mounting control components, organizing cable runs, and attaching lightweight equipment enclosures in HVAC, electrical, and general trade environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e400 stems per square inch for firm mechanical engagement\u003c\/li\u003e\n\u003cli\u003eRubber-based adhesive backing bonds to plastics, powder-coated surfaces, and low surface energy materials\u003c\/li\u003e\n\u003cli\u003eRated for 1,000 open-and-close cycles\u003c\/li\u003e\n\u003cli\u003e0.23-inch engaged thickness when mated\u003c\/li\u003e\n\u003cli\u003eTemperature resistance up to 120 degrees F\u003c\/li\u003e\n\u003cli\u003e2-inch-wide continuous roll, 50 yards per roll\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with acrylic, polycarbonate, ABS, powder-coated paints, polypropylene, and polyethylene surfaces.

Apply firm, even pressure along the full length of the strip after placement to ensure full adhesive contact. This fastener is rated for indoor use only and should not be exposed to outdoor conditions or temperatures above 120 degrees F. Cut to length with standard utility shears or a sharp blade.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Density\u003c\/strong\u003e: 400 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\u003eTemperature Resistance\u003c\/strong\u003e: Up to 120 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 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\u003eWeight\u003c\/strong\u003e: 7.15 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: 7100091141\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345311826226,"sku":"7100091141","price":903.33,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310518393.jpg?v=1782054370","url":"https:\/\/voomisupply.com\/products\/3m-7100091141-dual-lock-reclosable-fastener-sj3542-black","provider":"Voomi Supply","version":"1.0","type":"link"}
