The CARLISLE HARDCAST 310381 is a cover tape designed for sealing and protecting duct joints, seams, and related connections in HVAC ductwork systems. Supplied in a 6-inch-wide, 50-foot roll, it provides consistent coverage across standard joint widths in a single pass. At 26 pounds per roll, the product is sized for professional job-site use. HVAC technicians and sheet metal contractors use this tape as part of a complete duct sealing system, typically in conjunction with mastic or other sealants, to meet air-tightness requirements on commercial and residential duct installations.
This cover tape is applied over duct joints and seams where a reinforced or protective outer layer is required. It is well suited for use in forced-air HVAC systems during new construction or retrofit work. The 50-foot roll length supports continuous runs on large duct sections, reducing the number of splice points and keeping installation efficient. It is typically installed by licensed HVAC technicians or sheet metal workers on both supply and return air duct assemblies.
Designed as an OEM-style cover tape for use in residential and commercial HVAC ductwork sealing applications where a 6-inch-wide cover tape is specified.
Cover tape is installed by licensed HVAC technicians or sheet metal workers as part of a duct sealing assembly. Power down the air handling system before beginning duct work. Ensure surfaces are clean, dry, and free of debris before applying tape to promote proper adhesion. Follow local mechanical codes and manufacturer application guidelines for duct sealing systems.
