Shurtape SHUR-201885 Cloth Duct Tape 2in X 180ft Ul 181B-FX

Product Description

The SHURTAPE SHUR-201885 is a black printed closure cloth duct tape rated to UL 181B-FX and designed for sealing, seaming, and joining Class 1 flexible duct systems in HVAC applications. At 2 inches wide and 180 feet long, this roll provides enough material for a full day of duct connection work without mid-job interruption. The cloth backing delivers the tensile strength needed for connections that must meet UL requirements, flex duct manufacturer specs, and local building code standards. It bonds reliably to stainless steel and polyethylene surfaces, making it a dependable choice for air duct installation and splice work in both new construction and retrofit scenarios.

This tape is used in HVAC systems where Class 1 flexible duct is installed, including residential and light commercial air distribution systems. It is suited for sealing seams and making connections at duct-to-fitting and duct-to-duct junctions. The UL 181B-FX listing satisfies code requirements enforced by city and state building departments, as well as the adhesion and tensile strength standards set by flex duct manufacturers. HVAC technicians and sheet metal workers reach for this tape when a professionally finished, code-compliant closure is required on flexible duct assemblies.

Key Features

Compatibility

Designed for use in HVAC flex duct installations requiring UL 181B-FX listed closure tape, including sealing, seaming, and joining Class 1 flexible duct systems and air connectors.

Installation Notes

This tape is installed by licensed HVAC technicians and sheet metal workers during air duct system assembly or repair. The substrate surface should be clean, dry, and free of dust or oils before application to ensure full adhesion. Power down the air handling system before working on duct connections in enclosed or pressurized spaces. Verify that local building codes and the flex duct manufacturer's installation instructions accept UL 181B-FX listed tape before use on a given system.
