Hello to all from a newbie to this particular forum,
In case anybody else is still interested in this thread from a year ago, I discovered the same issue when I attempted to connect the collection adapter to the shroud. There are actually two issues. One, the shape of the shroud opening is neither circular, nor flexible enough, thus does not readily accept a standard 4" male connector even if the following (Two) was not an issue. Two, the saw's stand does not provide enough room between the shroud and the frame to fit the connector that SawStop themselves provide with their dust collection kit, which is evidently designed nearly exclusively for the cabinet saws despite that it is advertised (and the instructions imply) that it works with the contractor saw.
DRJZ1974 has come up with a nice solution.
I enjoy my SawStop contractor saw (awesome saw) and some basic ingenuity can guide one to a solution, but their dust collection kit was not really designed for it.
Looking forward to positive and enlightening woodworking discussions!
Cheers,
Ed
