But hoses are heavy and floppy, and getting them to stay put can be challenging. That's why we've designed our dust hose clamp hanger so you can easily attach the hose to your workbench, roller stands, stationary power tools, and more. Whether you're collecting lathe chips, chop saw dust, or drill press shavings, this dust collector hose holder will keep things in place so the dust goes where it belongs.
