Southwark Metal 73c161614 Rect to Round Transition 16x16x14

Product Description

The SOUTHWARK METAL 73c161614 is a rectangular to round transition fitting used in sheet metal ductwork applications. It connects a rectangular duct opening to a round collar, allowing a smooth transition between duct configurations. Fabricated from hot-dipped galvanized steel conforming to ASTM A653 CS Type B, this fitting is constructed at 28 gauge. The overall dimensions are 16 inches by 16 inches by 14 inches. It is sold as an individual unit and is installed by licensed HVAC sheet metal mechanics during residential and light commercial duct system fabrication or retrofit work.

This transition fitting is appropriate for forced-air HVAC systems where a rectangular plenum or trunk line must connect to a round branch duct or collar. Typical applications include supply air takeoffs from rectangular plenums and transitions at air handler or furnace discharge openings. The fitting is part of the Southwark 73C series, which is available in sizes ranging from 6 x 6 through 20 x 20 inches, with other sizes available upon inquiry. The collar height on this fitting is approximately 2 inches for collars up to 16 inches in diameter, and approximately 3 inches for collars 18 inches in diameter and above.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard residential and light commercial forced-air HVAC duct systems requiring a rectangular to round transition at plenum or trunk connections.

Installation Notes

Installation should be performed by a qualified HVAC sheet metal mechanic in accordance with SMACNA duct construction standards and applicable local mechanical codes. Disconnect and lock out the air handling unit or furnace before beginning duct work. Secure the fitting using sheet metal screws and seal all joints with listed duct sealant or foil tape to maintain system pressure integrity. Do not exceed the pressure class rating appropriate to the gauge and construction of the surrounding duct system.
