Works on my inlets
I have one of those hoses I use at the store. It works fine with my universal Hayden type inlets. Nutone wall ends are a tad bit smaller than standard but this one doesn't give me any trouble. I have tried a few switched NuTone hoses on my Hayden inlets and most don't get a strong enough connection to keep the vacuum running. I can still get standard hoses like that, that are universal fit. I don't know what kind of Power Head you have but Nutone handles have a higher button set that doesn't fit on the standard Eureka style wand.
