Standard Duct and Fittings

Deliver air for a range of HVAC applications, including exhaust and dust collection. Our basic duct, the round shape creates smoother, more efficient airflow than rectangular and oval duct. The male end is slightly smaller than the female, so sections join without clamps or tools.

Straight Collars

Link rectangular duct systems to equipment that uses round duct. Cut a hole, install the collar, and connect a piece of round duct.

Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.

Polyethylene Foam Gasket—The flange has an adhesive-backed gasket to bond the connection until you fasten with screws. The gasket also prevents leaks.

Rectangular Duct and Fittings

Maximize the space in close quarters, such as inside walls and ceilings. As rectangular duct sizes increase, they get wider but not taller. This shape is most often used for heating and cooling inside buildings. Components connect with brackets.

Straight Collars

Add a branch to an existing line of rectangular duct. Cut a hole in the duct, attach the collar by bending the tabs, and connect another piece of duct.

Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.
