Southwark Metal ATDRP446 Air-tite Round Pipe Saddle Takeoff with Damper 6 Inches

Product Description

The Southwark Metal ATDRP446 is a 6-inch Air-Tite Round Pipe Saddle Takeoff with Damper designed for residential and light commercial HVAC duct systems. This fitting connects a round branch duct to a rectangular main trunk duct, allowing airflow to be diverted from the main supply plenum or trunk line into individual room runs. The saddle-style design sits directly on the trunk duct and is secured in place, making installation straightforward for HVAC technicians and sheet metal contractors working on forced-air heating and cooling systems.

The built-in damper is a key feature of this fitting. It allows the installer or technician to regulate airflow to a specific zone or room without adding a separate balancing damper downstream. This simplifies the duct layout, reduces the number of parts needed, and gives the system more precise airflow control right at the takeoff point. Proper airflow balancing is critical in any duct system, and having a damper integrated into the saddle takeoff saves both time and materials on the job.

The flanged construction of the ATDRP446 provides a secure connection between the saddle and the round branch pipe. The flange helps seat the fitting firmly against the trunk duct and supports a tight, low-leakage joint. Reducing air leakage at duct connections improves system efficiency and helps maintain the designed static pressure throughout the duct network. This is especially important in systems where energy performance and comfort levels are priorities.

With a 6-inch diameter, this takeoff is well suited for standard branch duct runs serving individual registers or diffusers. Southwark Metal is a well-known manufacturer of HVAC sheet metal products, and the Air-Tite line is recognized for quality construction and reliable performance in the trade.
