What component delivers air to a register box?

• A. Boot
• B. Elbow
• C. Branch duct
• D. Stack

Answer: (C)

The component responsible for delivering air to a register box is the branch duct. In an air distribution system, branch ducts serve as the pathways that transport conditioned air from the main trunk line or supply duct to the specific areas of a building where registers, or air outlets, are located. This allows for the effective distribution of air throughout different spaces, ensuring consistent temperature and comfort levels. Each branch duct is typically connected to the main supply duct, and from there, it runs to the register box, where the air is finally released into the room. The design of branch ducts is crucial for optimizing airflow and efficiency, as they must be appropriately sized and routed to minimize resistance and pressure drops. While other components like boots and elbows play important roles in connecting and redirecting airflow in the duct system, it is the branch duct specifically that channels the air directly to the register box, making it the correct answer in this context.
