I wish there were. When it comes to commercial above the table dust collection, I have not seen any one that is as good as the SawStop dust collection blade guard. I am talking about dust collection effectiveness, ease of use and degree of obstruction. If anyone who knows a better product, please share.
This (non-commercial) one is probably better than SS's dust collection blade for effectiveness, but obviously it is too bulky for any cabinet saw:

Instead of magnet sheets, the stache can be used to cover the front opening of a cabinet saw, according to the video producer.
