    Question Drag chain for vacuum dust collection tubing?

    Is there anywhere I can find a drag chain that is designed to hold lightweight flexible spiral dust collection tubing about 6 - 8 inches or 150-200 mm in diameter?

    It's irritating that everything else for wiring on a commercial table CNC wood mill is installed in a drag chain, but the dust collection duct is just flopped randomly across the table because there's no drag chain big enough to hold it.

    Standard drag chains / energy chains become incredibly expensive for larger versions because they assume you will be stuffing it with heavy hydraulic hoses or electrical cables, but a dust collection tube weighs almost nothing.

    I don't need a drag chain that costs US$50+ per link at this large but lightweight size.

    I don't think it would be too practical to run the dust collection hose through a giant drag chain. It is much easier to hang it from the ceiling:

    That length of flex is terrible for dust extraction. Flex needs to be as short as possible. Flex destroys your flow / dust collection.

    Works fine for us, we have most our routers and panel saws hooked up with flex all the way from the dust extractor. We are losing some "sucking power" there, but what's left is enough.
