No need for clamps or connectors—duct and fittings have a male end that is slightly smaller than its female end for simple assembly.

A spiral seam gives this duct greater strength and rigidity than standard duct.

Fittings have gaskets which create a tight seal—you don't need to seal joints with coating or tape.

Weld flanges to equipment to start a run of duct.

Often added to existing systems, these gates install without disassembling duct. Also known as half gates.

Use in dust collection systems. The slide pushes through the top of the gate to clear debris.
