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.

Crush-Resistant Spiral Duct and Fittings

A spiral seam makes this duct strong and rigid. Fittings have male ends with a slightly smaller diameter to press-fit into duct.
Galvanized steel has good corrosion resistance. PVC-coated steel combines the strength of steel with the corrosion resistance of plastic. 304 stainless steel is more corrosion resistant than steel.

Use these components (sold separately) to put together a duct system to collect sawdust, chips, shavings, and granular material from woodworking operations. Hose clamps are available.
For maximum safety and to avoid a dangerous buildup of static electricity, you must use the grounding kit (sold separately).
If you need more information on designing and installing a dust collection system, order our book "Dust Collection Basics."
