Standard Duct and Fittings
No need for clamps or connectors—duct and fittings press-fit together. Male ends are crimped or tapered, making them slightly smaller than a female end for simple assembly.
Galvanized steel has good corrosion resistance. 304 stainless steel is more corrosion resistant than steel and aluminum.

Collars create branches from a rectangular duct. Cut a hole in the duct and use a collar to attach standard duct. Collar with polyethylene gasket is self-sealing because the gasket has an adhesive back. The flange has 1/8" dia. mounting holes.

Quick-Disconnect Duct and Fittings
Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.
Galvanized steel has good corrosion resistance. 304 stainless steel is the most corrosion resistant.
For technical drawings and 3-D models, click on a part number.
Adapters join quick-disconnect duct to other duct systems. Duct-to-duct with flange adapters provide a secure connection between duct. Duct flanges are also available.

Rectangular Duct and Fittings
Often used in tight spaces, such as in walls and ceilings, rectangular duct allows you to select larger sizes without increasing duct height. Duct and fittings have interconnecting ends that lock together with brackets.

Duct Flanges
Bolt flanges to equipment to start a run of duct. They can also create secure connections between two duct ends by mounting a flange to each end and then joining the flanges.
Steel, galvanized steel, and 304 stainless steel flanges are also known as angle rings.
Galvanized steel flanges have good corrosion resistance. 304 stainless steel flanges are more corrosion resistant than steel. PVC plastic flanges are chemical resistant and withstand harsh environments. They are compatible with Chemical-Resistant Duct and Fittings.
