Dust Right® Combo Port

This is the 3rd time I have purchased these (2 or 3 each time). They are excellent for my stationary power tools, and are a breeze to install and use. I would highly recommend these if you have the Dust Right system - if you do not, they do not work so well. They can be easily used with a 4" hose, and clamp, but these only fit well with the Dust Right system (from Rockler). I will definitely buy again when I need some more of these!

Perfect fit with the dust right hose fittings.

Works great

not very good
