I recently installed a dust control system in my shop and over-ordered some materials. I have 10 5-ft lengths of 5" (26 gauge) snap lock duct work that I purchased from Oneida. As many of you know, Oneida is not cheap, but finding a supplier of 5" duct is not easy. That said, the material from Oneida is $19.68 per 5-ft section (plus shipping, taxes, etc.), I will sell for $12.00 per section ($120 total). I do not want to sell piecemeal, so please note you will need to buy all 10 pieces (50 feet).
