About Duct Hose

A spiral seam makes this duct strong and rigid. Fittings have male ends with a slightly smaller diameter to press-fit into duct.

PVC-coated steel combines the strength of steel with the corrosion resistance of plastic.

Swivel Threaded-Rod-Mount Loop Hangers

These hangers have a swivel nut for adjusting direction after mounting. They're also known as teardrop hangers. Combine with a threaded rod or other fastener to hang from the ceiling. To mount, screw threaded rod into the threaded hole on top of the hanger. The hanging height can be adjusted after material is installed. PVC-coated steel hangers reduce wear on material.
