I bought this at an auction, so I do not know exactly what model it fits. Please look at all the photos with measurements and make your own decision. There is no returns on it for not fitting so make sure you double check everything what I do know is that it had two sets of brand new replacement blades in the box for a 15 S that I have listed separately if you’re interested but that’s why I’m assuming it goes to this. Powermatic 15HH-15S ?. It may go to something completely different, but be the judge for yourself thank you
