HealSmart Aluminum Ducting 4"x8ft

Great value for the money and very easy to install. I used this for high volume wood sander dust extraction, and the size was perfect for this application. It had to snake between the rafters in my shop, so the flexibility was perfect. It is thick and durable enough to handle the vacuum pressure. Regardless of how you use it, the wide ranging functionality of this product will meet your needs.
