In duct installations, securing sections of the trunk line is crucial for ensuring proper airflow and system efficiency. The use of S connectors and drive clips is standard practice in the industry. S connectors are designed specifically for joining two sections of duct while maintaining a secure and airtight seal. They fit snugly into the ends of the duct sections, allowing for smooth airflow without leakage.

Drive clips further enhance this connection by holding the duct sections firmly together. These clips are mechanically fastened to the ducts using screws or self-tapping fasteners, which effectively keeps the ducts aligned and prevents them from coming apart under pressure or vibration. Together, S connectors and drive clips provide a reliable means to create a strong, durable trunk line that is necessary for the effective performance of the HVAC system.

Other options, while they may have their uses in various applications, do not represent the standard method for securing trunk line connections in duct installations.
