Where are drive slips typically installed within a duct system?

Drive slips are typically installed on the shorter sides of rectangular ducts. This design choice facilitates proper alignment and connection between segments of ductwork, which is especially important in maintaining optimal airflow and minimizing potential leaks. The shorter sides allow for easier adjustments and tighter seals when connecting sections of duct, helping to ensure efficient operation of the HVAC system.

Choosing the shorter sides for drive slips also enables the duct sections to expand and contract with temperature fluctuations without compromising the integrity of the joint. This flexibility is crucial for maintaining the overall efficiency and effectiveness of the heat pump system.
