I have one of the Woodtek 4 bag dust collectors, with 3 4" inlets. When I put this in my shop, I did not envision it becoming hard to get to. I keep telling myself I will be moving it someday and running some PVC piping for my major tools. In the meantime, I just move a 20' flex hose between the tools by loosening/tightening the hose clamp. I saw this video from Izzy Swan over the weekend and have purchased some of these hose connectors from Magswitch, who now manufactures these. I'll give a review once I have them and have used them for a bit.
