This 4 inch by 10 foot hose pairs perfectly with dust extractors and dust collection systems to help fight respiratory illnesses caused by dirty workshops. Heavy-duty construction prevents leaks and tears in the hose while the contoured grooves provide maximum flexibility. The clear material helps users spot blockages during operation. Although this hose is specifically designed for the WEN 3403 1500 CFM Woodworking Dust Collector, its universal build will fit most other brands of extractors as well.
