Dust Collector Quick Connect 4"

I have nine woodworking machines in my shop that require dust collection. I never really cared to hard plumb all of them since some are moveable and who knows when I might want to change the layout. So, I just had a long 4” hose connected to my duct collector with a quick connect on the end, quick and easy to hook up to a machine. The store bought quick connect I had used for years developed a crack. Rather than wait for it to break altogether I designed this. It works great!
