Quick-Disconnect Duct and Fittings
 |
The fastest ductwork to disassemble for dust collection and other frequently cleaned systems. Join sections with quick-release clamps that open and close with a flip of the latch. Since you don’t need screws, welds, or tools, the installation time is half that of other duct types.
Adjustment Sleeves
 |
Close gaps between sections of duct without disassembling the whole line. To install these sleeves, cut the end of your duct and place the O-ring on the cut piece. Then, slide the sleeve on and clamp in place.
Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.
Corrosion-Resistant 304 Stainless Steel—The most corrosion-resistant metal duct we sell. It won’t rust or degrade in systems that exhaust chemical fumes or vent heat from industrial ovens and dryers.
