Which connectors are used to secure sections of a rectangular sheet metal duct to the main supply line?

The use of S connectors and drive clips is important in connecting sections of rectangular sheet metal duct to the main supply line due to their specific design that facilitates secure and effective joining of the ductwork. S connectors allow for a proper fit and alignment of the duct sections, while drive clips provide additional support by holding the sections tightly together to prevent any air leaks or disconnections. This combination ensures that the duct system is stable, which is critical for maintaining the efficiency of the HVAC system.

In contrast, while quick connectors can be beneficial for certain applications, they are typically more associated with flexible ductwork rather than rigid rectangular duct sections. Angle brackets are generally used for structural support but do not function in the same manner as connectors for securing ducts. Rivets are utilized in a variety of metal joining applications but are not commonly used for connecting duct sections in typical HVAC installations due to the need for removable connections for maintenance or adjustments. Thus, the choice of S connectors and drive clips is ideal for the specific task of securing sections of rectangular ductwork effectively.
