The tape measures 2 inches wide and 100 feet long, providing substantial coverage per roll. Its mastic-based adhesive conforms to irregular surfaces and maintains a durable, airtight seal across the range of temperatures and pressures common in residential and light commercial ductwork. HVAC technicians and sheet metal installers use this tape where a listed closure system is required for flexible duct connections.\u003c\/p\u003e\n\u003cp\u003eThis tape is suited for use on flexible air ducts in forced-air heating and cooling systems. It is applied at duct-to-collar connections, boot seams, and transitions where a UL 181B-listed closure is required by code or local inspection authority. Its silver foil-backed construction holds up in attic and crawlspace environments where temperature swings and mechanical stress are common. A single 100-foot roll covers a substantial number of connections in a typical residential installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUL 181B listed — meets code requirements for flexible duct closure systems\u003c\/li\u003e\n  \u003cli\u003e2-mil construction provides puncture resistance and conformability over duct fittings\u003c\/li\u003e\n  \u003cli\u003eMastic-based adhesive bonds to flexible duct jackets, sheet metal, and duct board\u003c\/li\u003e\n  \u003cli\u003eSilver color provides visual inspection confirmation of taped joints\u003c\/li\u003e\n  \u003cli\u003e100-foot roll length reduces roll changes during installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a UL 181B-listed mastic tape for use on flexible ducts and associated fittings in residential and light commercial forced-air HVAC duct systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician or sheet metal mechanic in accordance with SMACNA guidelines and applicable mechanical codes. Shut down the air handler and verify the system is depressurized before taping duct connections. Surfaces should be clean, dry, and free of dust or debris for full adhesive contact.
