I bought a couple of these for use around the shop. I got the bright idea to adapt one to my tablesaw when the flatter adapter I had on it stacked up with dust. I have a Rockwell/Delta Contractor's Saw, which is typical of many similar saws. I adapted the Big Gulp hood to the bottom of the saw and got an immediate improvement in dust collection. I have also found other uses around the shop for these fittings. Well worth the price.
