I must say that I was somewhat disappointed in this item. It is made out of cheap galvanized sheet metal, and looks to be worth about a quarter of what Delta is charging for it. Worse still, it does not fit my Special Edition Unisaw all that well -- there are significant gaps at the sides of the piece, and the bottom of the connector doesn't fit snugly against the dust ramp on the Unisaw. As a final indignity, they include the wrong type of screws to attach it to the saw. (I had to go buy two hex head bolts, washers, and nuts at the local hardware store in order to attach it.)I kept mine, because I do so much work with my Unisaw that I really need to attach my dust collector to it, but Delta definitely needs to go back to the drawing board on this one.
