This specific type of rectangular ductwork utilizes a unique connection method. Sections are joined by sliding one piece into another, typically with a slightly larger end fitting over a smaller end, and then secured. This design allows for flexibility during installation and often reduces the need for screws or other fasteners, saving time and labor. A common application is in HVAC systems for commercial and residential buildings.
The inherent adjustability offered by this connection style simplifies installation in tight spaces or around obstacles. It can also accommodate minor misalignments and variations in building dimensions. This method’s speed and efficiency can translate to lower installation costs compared to traditional flanged or welded ductwork. The reduced reliance on fasteners contributes to a smoother internal surface, improving airflow efficiency and potentially reducing noise levels. Though a relatively modern development in ductwork technology, this connection system has quickly become a popular choice for its practicality and cost-effectiveness.
