Review on 🌪️ BLACK POWERTEC 70198 Flexible Dust Collection Hose – 36-Inch Long, 2-1/2-Inch by Abhinav Drury

I bought these thinking I could add 4" dust fittings to complete my system. But they don't fit 4 inch dust fittings at all. UPDATE: I've adjusted them, but putting them on requires a special technique (which may need to be explained in the box). Start with a fully folded hose and press the ends of the fitting against the end of the hose. You should then stretch the hose and pull each ring of wire onto the fitting one at a time (fingernails work well for this) by sliding each ring onto the fitting one at a time.
