Made from black polypropylene, the strip measures 1 inch wide by 10 feet long and delivers an engaged thickness of 0.23 inches when closed. Rated for up to 1,000 closure cycles, it is suited for repeated attach-and-release applications where a secure mechanical fastening solution is needed indoors. Installation requires no tools beyond cutting to length and pressing the adhesive side firmly to the substrate.\u003c\/p\u003e\n\u003cp\u003eThis fastener strip is intended for indoor use across a wide range of assembly, mounting, and panel-attachment applications. It performs in low-temperature environments and is rated to withstand up to 120 degrees F. The adhesive is formulated to bond to many plastics including acrylic, polycarbonate, and ABS, as well as powder-coated painted surfaces and low surface energy materials such as polypropylene and polyethylene. Typical applications include securing access panels, cable management covers, instrument housings, and similar components where tool-free removal and reattachment is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e250\/250 stem density configuration delivers consistent mechanical closure force across the mating surfaces\u003c\/li\u003e\n  \u003cli\u003eRubber-based adhesive backing bonds to a broad range of plastics, powder-coated paints, and low surface energy substrates\u003c\/li\u003e\n  \u003cli\u003eRated for 1,000 closure cycles for long-term repeated use\u003c\/li\u003e\n  \u003cli\u003e0.23 inch engaged thickness for low-profile assemblies\u003c\/li\u003e\n  \u003cli\u003eTemperature resistance up to 120 degrees F with low-temperature performance capability\u003c\/li\u003e\n  \u003cli\u003eBlack polypropylene construction for UV-stable, chemical-resistant performance indoors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for bonding to acrylic, polycarbonate, and ABS plastics, powder-coated painted surfaces, and low surface energy materials including polypropylene and polyethylene.
