Where are the "drives" usually located on rectangular duct as a transverse connection?

The correct placement of "drives" as a transverse connection on rectangular duct is generally on the short side of the duct. This positioning is significant because it allows for easier access and better structural integrity when making connections between different sections of ductwork. By placing the drives on the short side, installers can ensure that the connections are tighter and reduce the likelihood of air leaks.

Additionally, positioning the drives in this manner helps with the overall alignment of the duct system, making it simpler to create a consistent and efficient airflow path. It also assists in maintaining the balance of the duct system, as the short sides are typically less obstructed and can accommodate additional fittings more effectively.

The other placement options, such as the long side or top of the duct, may impede airflow or create challenges when connecting with other components. The focus on the short side helps streamline the installation and optimize system performance.
