The 85041 SD 3-3/4"x78" Duct BLK 100 is a foundational element for constructing a robust and aesthetically pleasing HVAC/R line set cover system. This duct section is designed to enclose and protect the vital refrigerant lines, electrical wiring, and condensate drain hoses that connect indoor and outdoor HVAC units. Its 78-inch (6.5-foot) length provides ample coverage for typical residential and light commercial installations, safeguarding the line set from UV radiation, weather, and physical damage.
This line set duct is ideal for both new HVAC installations and upgrading existing exposed line sets, offering a clean and professional appearance to any building exterior. By providing a protective conduit, it helps prevent insulation degradation, reduces the risk of accidental damage, and contributes to the overall efficiency and longevity of the HVAC system. HVAC contractors and property owners prioritize this component for its protective qualities and ability to enhance curb appeal.
When purchasing this duct, ensure the 3-3/4" width is compatible with your specific line set dimensions and other SD series fittings (like elbows, couplers, and wall inlets). The 78-inch length allows for flexibility in routing. Matching the BLK 100 color/series code with other components ensures a uniform and integrated system. Always verify product specifications and compatibility with your HVAC system requirements before ordering.
